Why not run a cron job that goes off somewhat before the appliance timer
shuts the machine down that goes through the output of the 'status'
command and shuts down cron, getty, uucico, uuxqt, et. al. by sending them
each a ^C? That's one of the things my system-shutdown script does. It
would certainly seem to be inexpensive insurance!

The appropriate part of my script, which depends on ARP, GNU sed, and
other ugly things looks like:

[...]
;
; shutdown processes associated with uucp
;
path uucp:c bin: s: add
echo "Stopping uucico"
kill uucico
echo "Stopping cron"
kill dcron
echo "Stopping getty"
status | sed -n "s/.*getty/getty -0/p" | type to t:tmp.$$
;
; execute scriptfile
;
execute t:tmp.$$
delete t:tmp.$$
[...]

Where "kill" is a script that looks like:
.key process
.bra {
.ket }
;
; script file to kill process(es) by name
;
status | sed -n /{process}/s/Process/break/p | sed -n "s/:.*/ all/p" | type to t:tmp.$$
execute t:tmp.$$
delete t:tmp.$$
