No, some piece is missing, but we can not exit right away, we have to
send a SIGTERM to all children, then return to the main loop which will
wait a bit, then send a SIGKILL if children are not answering, then
finally exit. And we have to take note somewhere of the child exit
status to call exit with the same exit status. Will send a patch shortly.
