The standard sysvinit uses a signal handler on SIGCHLD to collect
all of its children which has died. I guesss that systemd does
nearly the same. If a normal process uses a signal handler it
should make sure that the signal handler is restarted (SA_RESTART)
and not blocked by any signal mask, also within the signal handler
should pick up all available childs.
