It looks like coypu is going to need manual intervention (ie, kill -9
on the leftover postmaster) to get unwedged :-(. That's particularly
disturbing because it implies that ServerLoop isn't iterating at all;
otherwise, it'd have noticed by now that the buildfarm script deleted
its data directory out from under it. Even if NetBSD's pselect had
forgotten to unblock signals, you'd figure it'd time out after a
minute ... so it's even more broken than that.
