> The *Frame* changes seem quite reasonable, but I'm curious as to why you changed CacheFrame.  Those changes look correct, but as far as I know we don't ever use CachedFrame in chromium (since we don't use the bfcache).  Did these changes have an effect on the behavior you were seeing in chromium?  Were you testing with the mac port?

It is a drive-by change when I grep through all places we ever detach a Frame/FrameView, and found out there are missing willDetach notification. Probably won't affect us. I'll remove those if it doesn't crash layout tests.
