XtDispatchEvent() is not re-entrant.  Therefore it is impossible to
write callback functions that perform a non-local goto (e.g. call
the C library function longjmp()).  I consider this a bug; it
should be possible to write callback functions that break out of
the current ``main loop'' (e.g. the callback associated with some
sort of ``quit'' button).
