  Is there anyway to write a function that will pop up a list
of items, let you select one, and return the index to you?
  I know how to use the athena list widget and popups, but
XtPopup returns immediatly and I don't know how to make the
function wait or block until the callback for the selection is called.
  I suppose I could poll some global variable, but there must be a better
way.  I am using Athena widgets, but I think Motif has a similar problem.
