This bug only appears to happen with plug-ins, so my current working theory is
that a plug-in registers a callback, then gets destroyed, and the process of
destroying the plug-in releases the WebCoreResourceHandleAsDelegate one too
many times, causing _sendCallBacks to fail when sending a message to a zombie.

The trick is figuring out the over-release path.  (I actually stepped through
the whole www.abc.com page load once with a breakpoint on
[WebCoreResourceHandleAsDelegate release] until I got the error, but I didn't
know exactly when it was coming, so I wasn't paying attention to the call
stacks just before the error occurred.  :(
