        - Fixed "Stack overflow crash in JavaScript garbage collector mark pass"
        http://bugs.webkit.org/show_bug.cgi?id=12216
        
        Implement mark stack. This version is not suitable for prime time because it makes a
        huge allocation on every collect, and potentially makes marking of detached subtrees
        slow. But it is an 0.4% SunSpider speedup even without much tweaking.
        
        The basic approach is to replace mark() methods with
        markChildren(MarkStack&) methods. Reachable references are pushed
        onto a mark stack (which encapsulates ignoring already-marked
        references). 
        
        Objects are no longer responsible for actually setting their own
        mark bits, the collector does that. This means that for objects on
        the number heap we don't have to call markChildren() at all since
        we know there aren't any.
        
        The mark phase of collect pushes roots onto the mark stack
        and drains it as often as possible.
        
        To make this approach viable requires a constant-size mark stack
        and a slow fallback approach for when the stack size is exceeded,
        plus optimizations to make the required stack small in common
        cases. This should be doable.

        I replaced mark() methods with markChildren() as usual. One
        optimization that is lost is avoiding walking detached DOM
        subtrees more than once to mark them; since marking is not
        recursive there's no obvious way to bracket operation on the tree
        any more.

        - JavaScriptCore part of fix for <rdar://problem/5300291> Optimize GC to reclaim big, temporary objects (like XMLHttpRequest.responseXML) quickly
        
        Also, as a side effect of optimizations included in this patch:
        - 7% speedup on JavaScript iBench
        - 4% speedup on "Celtic Kane" JS benchmark
        
        The basic idea is explained in a big comment in collector.cpp. When unusually 
        large objecs are allocated, we push the next GC closer on the assumption that
        most objects are short-lived.
        
        I also did the following two optimizations in the course of tuning
        this not to be a performance regression:

        1) Change UString::Rep to hold a self-pointer as the baseString in
        the unshared case, instead of a null pointer; this removes a
        number of null checks in hot code because many places already
        wanted to use the rep itself or the baseString as appropriate.
        
        2) Avoid creating duplicate StringImpls when creating a
        StringInstance (the object wrapper for a JS string) or calling
        their methods. Since a temporary wrapper object is made every time
        a string method is called, this resulted in two useless extra
        StringImpls being allocated for no reason whenever a String method
        was invoked on a string value. Now we bypass those.

        - fixed <rdar://problem/5300291> Optimize GC to reclaim big, temporary objects (like XMLHttpRequest.responseXML) quickly
        
        With this plus related JavaScriptCore changes, a number of XMLHttpRequest situations that
        result in huge data sets are addressed, including a single huge responseXML on an XMR done

        In addition to the GC changes in JavaScriptCore, I changed responseText to be stored as a

        share the buffer (indeed multiple intermediate responseTexts can share its buffer).

        (1) Added some missing JSLocks, along with related ASSERTs.
        
        (2) Fully implemented support for objects that can only be garbage collected
        on the main thread. So far, only WebCore uses this. We can add it to API
        later if we learn that it's needed. 
        
        The implementation uses a "main thread only" flag inside each object. When 
        collecting on a secondary thread, the Collector does an extra pass through 
        the heap to mark all flagged objects before sweeping. This solution makes
        the common case -- flag lots of objects, but never collect on a secondary 
        thread -- very fast, even though the uncommon case of garbage collecting
        on a secondary thread isn't as fast as it could be. I left some notes 
        about how to speed it up, if we ever care.
        
        For posterity, here are some things I learned about GC while investigating:
        
        * Each collect must either mark or delete every heap object. "Zombie" 
        objects, which are neither marked nor deleted, raise these issues:

            * On the next pass, the conservative marking algorithm might mark a 
            zombie, causing it to mark freed objects.

            * The client might try to use a zombie, which would seem live because 
            its finalizer had not yet run.

        * A collect on the main thread is free to delete any object. Presumably, 
        objects allocated on secondary threads have thread-safe finalizers.

        * A collect on a secondary thread must not delete thread-unsafe objects.

        * The mark function must be thread-safe.
        
        Line by line comments:

        * API/JSObjectRef.h: Added comment specifying that the finalize callback 
        may run on any thread.

        * JavaScriptCore.exp: Nothing to see here.

        * bindings/npruntime.cpp:
        (_NPN_GetStringIdentifier): Added JSLock.

        * bindings/objc/objc_instance.h:
        * bindings/objc/objc_instance.mm:
        (ObjcInstance::~ObjcInstance): Use an autorelease pool. The other callers 
        to CFRelease needed one, too, but they were dead code, so I removed them 
        instead. (This fixes a leak seen while running run-webkit-tests --threaded,
        although I don't think it's specifically a threading issue.) 
        
        * kjs/collector.cpp:
        (KJS::Collector::collectOnMainThreadOnly): New function. Tells the collector
        to collect a value only if it's collecting on the main thread.
        (KJS::Collector::markMainThreadOnlyObjects): New function. Scans the heap
        for "main thread only" objects and marks them.

        * kjs/date_object.cpp: 
        (KJS::DateObjectImp::DateObjectImp): To make the new ASSERTs happy, allocate 
        our globals on the heap, avoiding a seemingly unsafe destructor call at 
        program exit time.
        * kjs/function_object.cpp:
        (FunctionPrototype::FunctionPrototype): ditto

        * kjs/interpreter.cpp:
        (KJS::Interpreter::mark): Removed boolean parameter, which was an incomplete
        and arguably hackish way to implement markMainThreadOnlyObjects() inside WebCore.
        * kjs/interpreter.h:

        * kjs/identifier.cpp:
        (KJS::identifierTable): Added some ASSERTs to check for thread safety 
        problems.

        * kjs/list.cpp: Added some ASSERTs to check for thread safety problems.
        (KJS::allocateListImp):
        (KJS::List::release):
        (KJS::List::append):
        (KJS::List::empty): Make the new ASSERTs happy.

        * kjs/object.h:
        (KJS::JSObject::JSObject): "m_destructorIsThreadSafe" => "m_collectOnMainThreadOnly".
        I removed the constructor parameter because m_collectOnMainThreadOnly,
        like m_marked, is a Collector bit, so only the Collector should set or get it.

        * kjs/object_object.cpp:
        (ObjectPrototype::ObjectPrototype): Make the ASSERTs happy.
        * kjs/regexp_object.cpp:

        This is a known issue with stack overflow during the mark phase. It's
        not related to threading.

        - added forwarding headers for the new Forward.h and HashForward.h files

        * kxmlcore/Forward.h: Added.
        * kxmlcore/HashForward.h: Added.

WebCore:

        Rubber-stamped by John Sullivan (except for pbxproj change).

        - updated to use the new Forward.h and HashForward.h headers
        - moved the showTree debugging functions out of the WebCore
          namespace so they are easier to call from gdb, and renamed
          the showTree member functions so they don't get in the way;
          now you can do "call showTree(x)" in gdb and it just works
        - removed a lot of unneeded includes

        * WebCore.xcodeproj/project.pbxproj: Fixed a lot of paths that
        were not relative to the enclosing group.

        - fix http://bugzilla.opendarwin.org/show_bug.cgi?id=6505
          retire APPLE_CHANGES from JavaScriptCore

        * JavaScriptCore.xcodeproj/project.pbxproj: Removed both
        APPLE_CHANGES and HAVE_CONFIG_H from all targets.

        * README: Removed. This had obsolete information in it
        and it wasn't clear what to replace it with.

        * kjs/collector.h: Removed an APPLE_CHANGES if around something
        that's not really platform-specific (although it does use a
        platform-specific API at the moment).

        of the runtime.h header. Even though that header isn't needed at the
        moment on platforms other than Mac OS X, the conditional stuff should
        be in the header itself, not in this one client.

        * kjs/math_object.cpp: (MathFuncImp::callAsFunction): Removed some
        code inside APPLE_CHANGES. I'm pretty sure this code isn't needed on
        any platform where pow is implemented corrrectly according to the IEEE
        standard. If it is needed on some, we can add it back with an appropriate
        #if for the platforms where it is needed.

	Radar 2890573 - JavaScriptCore needs to be thread-safe

	Actually this is only a weak form of thread-safety - you can safely
