WebProcess crashes handling repeated NetworkProcess crashes

1 - The NetworkProcess crashed once while lots of loads were in progress.
2 - The WebProcess saw this, and started failing out all of the resource loaders, which involved messaging back to the new NetworkProcess in a tight loop.
3 - The new NetworkProcess crashed (ASSERTed) trying to remove a loader that didn't exist.  This was fixed in http://trac.webkit.org/changeset/140852 but some other symptom could arise causing similar behavior.
4 - The WebProcess was still trying to fail out these resource loaders in a tight loop, and in the middle of this loop the connection once again became invalid from the crash in step 3.
5 - WebProcess crashed as a result.
