 Hmm, CMSG_SPACE() isn't constant on NetBSD as far as I can tell. Naively we
 could do this, but I haven't read enough of the surrounding code yet to know
 if its safe.
 
    1021        /* Sanity check the control message header. */
    1022        if (cm->cmsg_type != SCM_RIGHTS || cm->cmsg_level != SOL_SOCKET 
||
    1023            cm->cmsg_len > control->m_len)
    1024                return (EINVAL);
