--- Comment #20 from Andreas Kling <akling at apple.com> ---
This caused various problems with ImageLoaders getting stuck with m_hasPendingLoadEvent=true, which prevents the garbage collector from deleting these elements.

I'm rolling the change out since it wasn't clearly fixing a bug in the first place.

I suspect that the main cause of problems is that FrameLoader::stopAllLoaders(), which is called on navigation, ends up causing pending CachedResources to become cancelled, but cancelling a CachedResources fires notifyFinished(), not imageChanged().
