Don't forget that if you use a flock(), there is a race condition when
two seperate processes are checking to see if the daemon is running
where one process may think it's not running (its attempt to lock the
pidfile succeeds) and the other process thinks it's running (since its
attempt fails since the first process hadn't released its lock yet).
