>Description:
	problem #1: system hanged while running mrouted when IETF
                    channel 1 resumed after first session's break
	            hang resulted in grey screen and total lockup
	 	    requiring push of reset button
        problem #2: system rebooted (no panic, no sync, just reboot)
                    while running sdr, vic, vat, mrouted, netscape
                    and a couple of make cleandirs in source directories
                    and a sup.  repeatable.
>How-To-Repeat:
	boot kernel; rc.conf has mrouted=YES, so mrouted runs
	run sdr.  choose IETF channel 1.  join audio & video.
	watch for a while.  do some disk-intensive things (haven't
	yet tried CPU-only load).  watch crash.  curse.
 		
>Fix:
	don't run mrouted
	(i will also try latest -current sources and check bugs database)
