Um, you're right, I hadn't done the test properly.  If I have an open
psql session across TCP and do pg_ctl stop -m fast, then I can't
start a new postmaster until the socket goes out of CLOSE_WAIT state.
Which, if I just leave the psql session sit there, seems to mean
"indefinitely" ... so it's even worse than just a TCP timeout.

So the notion of not using SO_REUSEADDR seems a nonstarter, and we
probably have to go with Magnus' global-object hack.
