I'm not really particularly worried about that case. By that logic,
we could not use quickdie at all, because any part of the system
might be doing something that wouldn't survive being interrupted.
In practice the code path isn't sufficiently used or critical
enough to be worth trying to make that bulletproof.
It does strike me that we might someday add code to the postmaster
to SIGKILL processes that fail to exit in a reasonably prompt fashion
after SIGQUIT, on the theory that they might be stuck in something
like this. But for now, I'm more interested in a one-line fix that
will deal with the actually observed case ...
