We are developing real-time graphical simulations that update the scene
at 16 hz or higher.  One problem we have is that at some definite period
in time (of which I do not know) we can "hear" the disk being accessed.

We are certain that it is not the software, and we have turned off cron,
and some other processes.  A "ps -e" outputs the following on a 4D70-GT:

PID	TTY	TIME	COMMAND
0	?	0:00	sched
1	?	2:32	init
2	?	0:03	vhand
3	?	0:00	mhand
4	?	0:01	bdflush
806	console	0:01	grcond
74	?	0:00	inetd
122	ttyd1	0:00	getty
43	?	0:00	syslogd
67	?	0:00	routed
814	console	0:01	csh
73	?	0:00	portmap
813	console	7:22	wsh
2361	console	0:00	ps
808	keybd	11:12	news_ser

Any ideas?
