  | The same goes for the job table right?

Yes, though there's no posix explanation for that (no expectation
there that code would ever want to examine it).

  | None of ash derivatives (including
  | netbsd sh) seems to do that right though. `( sleep 3 & ( sleep 1 & wait )
  | )' hangs for three seconds instead of one, which doesn't happen on other
  | shells.

This is fixed in the current NetBSD sh, it waits for 1 second there, just
as if the job table was immediately cleared in the sub-shell.   I forget now
just how long ago that fix was installed, or if it got pulled up to the
netbsd-9 branch (ie: whether it can be expected in a reasonably up to date
9_STABLE version of sh).

Hmm - I just checked, that was fixed years ago, the fixed version should be
in NetBSD 8.1 and anything later (but not 8.0 or earlier) ("later" includes
everything netbsd 9 and more recent).
