The other job enumerations (for terminating jobs and sending
completions) do it for children first on then for parent. Do you know
that this should not be the case for job pids? I don't know if the pid
sort order is important for anything or consistent on Windows, but if
not testing the order explicitly I'd suggest to enumerate in the same
order as in the other places.
