An even smaller patch.  Find your restart script (either the sh or csh
one, it doesn't matter).  Go to the line that invokes `moo':

	nohup ./moo $1.db $1.db.new $2 >>& $1.log &

and add another line:

	echo $! > $1.pid

Whenever you put something in the background with `&', the shell saves
the pid of the command and you can access it with `$!'.
