AUDIO_DRAIN is used a lot, so I'm just going to clarify which one I did
comment out!

It is in dda/sun/ausuni.c at line 948 (1.6c codebase):

/* callback */
static void
disableProcessFlow()
{
#ifdef DEBUGLOG
	fprintf(stderr, "disableProcessFlow()\n");
	fflush(stderr);
#endif

	signalEnabled = AuFalse;
	ioctl(devAudioCtl, I_SETSIG, 0);	/* disable signal */
//	ioctl(devAudio, AUDIO_DRAIN, 0);	/* drain everything out
*/
	if (relinquish_device)
		closeDevice();
}

This actually dropped the binary size of nasd a lot for one line:

28516853  380 -rwxrwxr-x   1 richf    ukit       383504 May 18 11:00
./server/nasd
28768386  420 -rwxrwxr-x   1 richf    ukit       424608 Apr 26 10:14
./server/nasd.bak

I suppose the sensible thing to do would be for some other Solaris users
to test it out?

I've been using it a lot, and it has been working great. I can't get it
to hang at all, I can even play stuff from Linux ok!
