Yes, I mentioned that problem --- it's not new, at least 5.5 behaved
that way, and it's related to the fact that we have STAT_NOPRINT
associated with the subjob, which is what's actually being suspended.
I'm not sure how to fix this without unleashing a torrent of new
messages, but it's possible the key is ensuring the superjob and subjob
are aligned and printing a message if we update both --- since the point
here is to pretend to the user that they're acting as a single job.
(They bloody aren't, I can tell you...)
