Work around CFErrorGetDomain error or don't trigger it #410

The CFErrorGetDomain crash is something that we need to work around or not 
trigger.

This happens pretty often for me too.  Here's another crash log.

Huzzah! A reproducible case.  Using at least certain (tested with MonoWhite and 
Mono 2.0), if not all webkit styles, Growl will crash with this error when 
under heavy load of incoming notes, as the URL loader hangs trying to access a 
cache object synchronously with the main thread.  

The fault lies in GrowlWebKitImageProtocol - (void)startLoading where we 
dispatch_sync() to the main thread.  Will fix for 1.4.

have moved all access to the image cache for webkit behind a private concurrent 
queue, reads are done with dispatch_sync, and writes (add/remove) are done with 
dispatch_barrier_sync.  If the main thread was being inundated by notifications 
to process, it caused enough hang waiting for the URLProtocol that it was 
causing errors.  This was pushed to default in the dev repo as [5c7f5f4f8d95].

Marking this as started, we need to test this thoroughly, to make sure that we 
have not introduced any further issues with webkit displays.

I have yet to see a crash using this fix, an I have been exclusively using mono 
since implementing this.  I am going to mark as FixedInSource, however, let be 
sure it gets testing in Beta
