I meant "internal to cygwin".  The SO_LINGER change only affects a socket
that is used by cygwin.  I think it is possible that reverting that change
might have slowed down select enough that it made things appear to work,
though.

Ok.  I would be interested in seeing if all of the changes that I made
affect PostgresSQL.

Good.  That makes sense.  I should have read the description of SO_LINGER
before I made the change for AF_UNIX sockets.  If I had, I never would have
considered it.
