	I did that, but then get stuck at the while loop where I
	wait for expose events etc.

	while (1) {
	  XGetNextEvent(display, &event)
	  switch (event) {

		case Expose:

	...
	etc...

	} /*of while*/

	Basically, I can't get to call XGetNextEvent(display_1, &event)
	for each of the windows (i.e displays) in PARALLEL. Also, I can't
	call them one after another, since if I have


	XGetNextEvent(display_1, &event_1);
	XGetNextEvent(display_2, &event_2);

	and there is no event on display_1 while lots of events were
	being generated on display_2, then this would bomb.

	Any suggestions ?
