    The original intent of SO_REUSE was to allow the reuse of a TCP port
    before the FIN_WAIT timeouts had happened, so that daemon could be
    restarted without having to wait several minutes.  This use of it
    with UDP sounds dubious and ill-advised.  Why not just use different
    port numbers if you need multiple server instances?
