Hey, it just occurred to me that always checking for $SSH_CLIENT will be a
problem if somebody wants to start a normal background daemon from an
interactive ssh session, or even if they've restarted inetd from one.
What's a reliable way of determining on the server side that it's been
started from ssh? Maybe we could set another global in start_daemon()
