I asked how I could write a routine that would pop up a widget and *block*
until the user closed the widget.

kit@athena.mit.edu (Chris D. Peterson) answered a different question:
[	How can I lock out events in the rest of my applicaion 
  while processing an error condition? ]

He suggested using XtPopup (widget, XtGrabExclusive), and referred me	
to the R3 toolkit docs.  Unfortunately, I don't have the R3 documentation
yet, but my intuition, the R2 documentation, and the R2 source code all seem
to indicate that that routine will not block.  It will just perform
the appropriate grabs to ensure that none of my other widgets' callbacks
get called.

What I want is to write a routine that does not return until a widget
has been closed.  Is that what XtPopup does?
