Ah-hah. We probably ought to document that as a possible source of
failure in the parallel regression tests. I think the present script
will start as many as 20 parallel tests, which means 60 parallel
processes under your userid (a backend, a psql, and probably an owning
shell process for each psql). Add in the postmaster, your own shell,
a couple random make subprocesses, and you got trouble.

You should find that random fails only, um, randomly. If it fails
every time then there's a problem.
