There might be a problem if the window thinks that the freed object is
still its delegate and tries to send it a message.  I would guess that
after the windowWillClose: method returns the window is done with
its delegate.  If you want to be on the safe side you could set
the window's delegate to nil in windowWillClose:, or use
	[NXApp delayedFree:self];
in the windowWillClose: method to free your document.  The document
will be freed just before NXApp tries to get the next event.
