When I map a widget, using XtMapWidget, how can I wait for all the expose
events to be generated. I want to do the following:

void map_and_wait (w)
    Widget w ;
{
  XtMapWidget(w) ;
  ProcessEvents(w) ;
  return ;
}

When map_and_wait completes, I do not want (in general), for any more
expose events to come along in the pipeline. It's okay if it 
occasionally, but rarely happens -- I'm trying to solve a double
repaint problem.  I know I'm having the problem because my program
is poorly structured, i.e., not completely event generated, but there's
not much I can do about that now.

Thanks.
