Working on it.  The problem is due to the fact that the standard Aqua Tk 
on OS X is itself an official OS X app and creates the menu bar with 
default menu options including a standard application Quit.   I think I 
see how to intercept that.

I suggest we move the discussion to the bug tracker 
(http://bugs.python.org/issue10107).
