Right:

	% cat .logout
	tf=/tmp/k$$
	jobs >$tf
	if (! -z $tf) then	# there are jobs
		jobs >$tf.1	# rerun it to dump `Done' jobs
		grep -v Stopped <$tf.1 >$tf; rm $tf.1
				# cannot use a pipe here
		if (! -z $tf) then	# there are running jobs
			eval `echo kill -1; sed 's/.\([0-9]*\).*/%\1/' <$tf`
		endif
	endif
	rm $tf

Warning: I have not tested this and it may run afoul of various
csh quirks.  The important trick is to run `jobs >file', not
`jobs | command', as the latter runs `jobs' in a subshell and
thus produces no output (although `jobs | <any-csh-builtin>' is
good for a laugh :-) ).
