I like it!. This certainly reduces some piping but as long as it is not
integrated upstream it will only become more of a responsibility on
FreeBSD's behalf to maintain it. If someone has the original authors email
address I would say lets include him on this and see what he thinks.
This would probably be the same for the pkill thread that I am involved in
to. CC'ing responsible party for that thread.
This message was supposed to arrive 9 hours ago but there was some ISP
problems that prevented me from sending it.
