Do we know if KVO observing keeps weak references to observed

interested in observed objects atm) in a GC-only application?
No, you need to make sure you call -removeObserver:forKeyPath: at
some point. For custom views I usually do this in -
removeFromSuperView but if necessary you could put it in a -finalize
block.
Note that in the non-GC world, you can't do that in -dealloc (since
the KVO "warning" about deallocating something that is still be
observed happens before the call to dealloc), so it's unclear if there
isn't some similar helpful warning before -finalize is called...
