That's what I thought.  So, if you start "emacs -Q" and then manually
start the server, does Emacs hang when exiting right after that?

That's expected, because this code near the place where the main
thread was stuck:

  if (winsock_lib != NULL && winsock_inuse == 0)
    {
      /* Not sure what would cause WSAENETDOWN, or even if it can happen
         after WSAStartup returns successfully, but it seems reasonable
         to allow unloading winsock anyway in that case. */
      if (pfn_WSACleanup () == 0 ||
          pfn_WSAGetLastError () == WSAENETDOWN)
        {

clearly shows that winsock_inuse must be zero, which means we already
closed all the socket connections.  The question is, why the reader
thread of one of these connections is still waiting?
