          in WebCore::TimerBase::nextFireInterval() const + 100 (Timer.cpp:188)

        Test: fast/dom/Window/redirect-with-timer.html

        * platform/Timer.h: Made isActive no longer inline. Added inHeap function.
        * platform/Timer.cpp: Changed assertions to use inHeap function for clarity.
        (WebCore::TimerBase::isActive): Return true for timers that are ready to fire.
        They have a next fire time of 0, but they should still be considered active.
        (WebCore::TimerBase::checkConsistency): Correct the consistency check. The new
        rule is that timers with a next fire time of 0 are not in the heap, and all other
        timers are.
