	i am writing a widget which is a subclass of composite.
When I remove some of its child widgets, I get an expose event per
call to XtDestroyWidget. Since I remove many widgets at a time,
I would like to be able to get the first expose event, and then
get rid of the rest.
(Note: by expose events I mean calls to my ChangeManaged routine which
I assume is called by the Xtoolkit when an expose event arrives).
Does the toolkit support such a thing? Or do I need to go down to
the Xlib level and flush the events myself?

What I tried to do, and did not work due to the asynchronous nature of X, ids
to add a flag which is set to false when I start destrying widgets and
set to true when done. This flag is tested in my ChangeManaged routine.

Thanks,

/Luis
