Reviewed by David Levin.

Source/WebCore:

Covered by the existing tests.

* fileapi/FileStreamProxy.cpp:
(WebCore::FileStreamProxy::startOnFileThread):
* platform/network/BlobRegistryImpl.cpp:
(WebCore::BlobRegistryImpl::createResourceHandle):
* platform/network/BlobResourceHandle.cpp:
(WebCore::BlobResourceHandle::BlobResourceHandle):
(WebCore::BlobResourceHandle::cancel):
(WebCore::delayedStartBlobResourceHandle):
(WebCore::BlobResourceHandle::start): Keep BlobResourceHandle alive
till the delay function is called.
(WebCore::BlobResourceHandle::doStart):
(WebCore::doNotifyFinish):
(WebCore::BlobResourceHandle::notifyFinish): Notify the client via the
standalone function to prevent the handle from being disposed immediately
by the client which will make the calls in the stack that're still bound
to the handle suffer.
* platform/network/BlobResourceHandle.h:
* platform/network/ResourceHandle.h: Change cancel() to virtual so that
BlobResourceHandle::cancel will be called when we abort a FileReader.

LayoutTests:

* platform/gtk/Skipped: Enable the flakey test that has been fixed.
