This seems to eb a real bug, so lets move teh discussion to this mailing 
list.

My impression after a short inspection is that the problem comes from 
the fact that a menu allways registers itself with the notification 
centre, which in turn will keep a reference to the object thereby 
keeping it alive. But I might be wrong here, as many classes in GUI use 
a similar pattern and would thereby be living longer than expected. 
Coudl somebody with mre knowledge of the implementation of 
NSNotificationCenter comment on this?

Than this problem would even exist in the above code if the menu is only 
created and released later. Is this true?
