   This is similar to the loop I had in the dot.c program
   If your program does need to do anything while waiting for
   messages though you should use

	for (;;)
	{
		Wait(1<<w->UserPort->mp_SigBit);	/* wake up when message there */
		if (message = (......
			etc.
	}

	This will be much more fair to those other programs and to intuition
	as well.
