Sure, but when you select the Quit menu from the Dock it sends a -(id)
terminate:, so you'll need to send a -stop from here. Or so I believe,
that was the question asked :-)

We don't support Garbage Collection nor Objective-C 2.0 there, so it's
no big deal :-) The overhead to support garbage collection without
leaking is too important to be considered for a near future.
