Re: dealloc methods not being called?

AppKit does an optimization where at app shutdown time, it stops
dealloc'ing things.

It does make app quitting faster, but it means that if your deallocs
have side effects, the side effects will never occur. It also makes leak
tracking difficult if you try to do a full-on leak check at application
shutdown (something which many C++ apps do, but I've never seen done in
ObjC).
