:and then a lot of junk text (I appended /etc/rc and /etc/rc.network). Then,

:
:	nroff -ms foo.ms 2>&1 | less

:and quit 'less' straight away, the whole system seems to lockup.  ^T
:worked (sometimes), and showed troff using lots of system time (no user
:time). ping from another host worked, ctrl-alt-esc dropped into DDB ok,
:but that was about all. (ctrl-alt-del didn't work.)

:Of course, when it first happened I wasn't trying to process /etc/rc*
