Odd. I think we had to add it to make the test pass under some
situations, so I don't think we can remove it, but I'd have to research
why it is failing in other situations. It may stem from the history of
whether the test is being run from another session leader process, and
that may differ according to whether make is running the test or you are
doing it by hand.

Nice removal of an extra malloc.
goto error;

Safe, since we check msg for NULL later.

Maybe worth logging a warning if we see the failure, but since this is
test code, I'm also okay if we just ignore it (as long as the test still
passes, of course).
ACK.
