Subject: Improve postmaster's behavior if an accept() call fails.  Because the
 server socket is still read-ready, the code was a tight loop, wasting lots of
 CPU. We can't do anything to clear the failure, other than wait, but we
 should give other processes more chance to finish and release FDs; so insert
 a small sleep. Also, avoid bogus "close(-1)" in this case.  Per report from
 Jim Nasby.
