** PopDownBugPatch
**
** Under some circumstances, popping down a dialog and its parent in
** rapid succession causes a crash. This routine delays and
** processs events until receiving a ReparentNotify event.
** (I have no idea why a ReparentNotify event occurs at all, but it does
** mark the point where it is safe to destroy or pop down the parent, and
** it might have something to do with the bug.) There is a failsafe in
** the form of a ~1.5 second timeout in case no ReparentNotify arrives.
** Use this sparingly, only when real crashes are observed, and periodically
** check to make sure that it is still necessary.
