   Use XCheckIfEvent.  Have your predicate *always* return False. 

   Call it ugly, call it a kludge, but it works and it's portable.  Yes,
   it means you always walk all the way through the event queue .... 


Sorry,  should  have  mentioned this as an option. The disadvantage is
walking the entire list each time, something I didn't want to do.
