I need to have a sequence of sounds played out.  Each sound is under a
second long, and I need a couple of seconds pause between successive
sounds.

It seems simple enough, but I can't get it to work.  The program hangs on
around the 4th sound (depending on what the pause is).

I tried (under 1.0):

    1.	Doing it in an Application, and in a simple program

    2.  Using and not using -didPlay: in a delegate, which, as far as I
	can tell, never gets called (I put printf's in it, but never got
	any output).

    3.	Using no delay, using usleep() for delay, and using

	    for (startTime = time(0); time(0) < startTime + delay; ) {
		cthread_yield();
	    }

	for delay.

And, since setting sound fields of buttons in IB does have the desired
effect (clicking on all the buttons sequentially played all the sounds), I
even tried:

    4.	Using a dummy button, assigning sounds to it (with -setSound:, one
	at a time), and doing a -performClick: on it.

Like I said, the task seems simple enough.  Can this be done?  What's the
trick?
