Subject: [PATCH 8/8] service: don't report alien child as alive when it's not
When a sigchld is received from an alien child, main_pid is set to
0 then service_enter_running calls main_pid_good to check if the
child is running. This incorrectly returned true because
kill(main_pid, 0) would return >= 0.
This fixes an error where a service would die and the cgroup would
become empty but the service would still report as active (running).
