I could just be blind or ignorant, but I can't see any reason offhand why that process wouldn't be expected to need to be stopped in just the same way as those running under other user IDs. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man. -- George Bernard Shaw
