There is nothing sacred about XtMainLoop.  It simply gets an event
and dispatches it.  So just build your own main loop which checks to
see if any input is present before attempting to do the get/dispatch
sequence, and generates your graphics output.

You probably could do other things like build a widget which requests 
periodic timeouts, but this seems simpler.
