Note that in the non-GC world, you can't do that in -dealloc (since

called...
Actually, I just checked this and you're right, calling -
removeObserver:forKeyPath: in a -finalize method triggers a warning.
You would need to do this elsewhere, although the documentation is
particularly scant as to exactly where.
In general, -finalize should not be used to manage scarce resource nor
muck around with the app's object graph, including tearing down
observations and the like.
You will likely want to have some kind of an "I'm done with you, tear
yourself down at this known, predictable, good time to do so" method.
An -invalidate or -disconnect or -done or the like.
