    Prevent multiple Windows pmcd processes binding to same port.
    
    Follow through on the advice offered by MSDN on the setup
    of server sockets (via socket options) for daemons prior to
    bind.  This change prevents, in particular, multiple pmcd
    processes from being able to start and bind to the same port
    simultaneously (with "unspecified" results).  Subtle, nasty
    difference between Windows sockets APIs and everyone elses.
