	This posting apparently didn't make it out yesterday -- sorry if it
	actually did.

	I have an application which has various widgets which need to perform
	miscellaneous clean-up/housekeeping tasks before quitting.  To this
	end, I have registered appropriate destroy callbacks (XtNdestroyCallback
	list) with the widgets in question.  I expect these to be called when
	I explicitly destroy the topmost widget in the tree before quitting.

	So far, I have had no success -- the destroy callbacks are not executed
	at all.

	Is there something fundamentally wrong with my assumption?  Any tips
	would be greatly appreciated.  Thanks in advance.
