Okay, thanks, I've got that fixed up now.

SH> Dan, do you have any testcases (even just descriptions of how to

Yeah, I've got a big ugly test program that I've rolled automatic
tests for most scenarios into.  Here's the usage output of the test.
I'll get it cleaned up and posted too:

  Usage: ./testprog [-t (s|d)] [-wn] TEST
  Where:
    -t s, -t d:             Select STREAM or DGRAM sockets
    -w:                     Wait for a response before restarting
    -n:                     Don't terminate the test on successful restart
  
  Where TEST is one of:
    --unix_pair:            Pair of sockets using socketpair()
    --unix_unlinked:        Listen socket with an unlinked path
    --unix_pair_path:       Pair of sockets using paths
    --unix_pair_abstract:   Pair of sockets using abstract names
    --unix_inflight:        Pair of sockets with data in flight
    --unix_inflight_closed: Pair of sockets, one side closed after preflight
    --unix_midaccept:       Listen socket with unaccepted peer
    --unix_fdpass:          Attempt to pass an FD
    --unix_passcred:        Attempt to pass credentials
    --unix_path:            Post-restart path-based connect to listen socket
    --unix_abstract:        Post-restart abstract connect to listen socket
    --unix_path_unlink:     Like pair_path, but unlink socket before restart
    --unix_deadpeer:        Close peer socket with data in flight
    --unix_testopt:         Unix socket setting and testing for a sockopt
    --unix_anoninflight:    Inflight data with unconnected DGRAM sockets
    --inet_connected:       Pair of localhost INET4 sockets
    --inet6_connected:      Pair of localhost INET6 sockets
    --nonet:                No network, just a simple loop
    --sendmail:             Try to start up sendmail and checkpoint it
