    Yes, good idea, I'll send the patch in a minute.

    But now I see I didn't read your message to the end,

    Unless I missed something again, "nothing more" can't work. We still
    need this patch (re-sended). We still need to free sigqueue if it is
    not queued, and we must not dequeue it if it is queued - otherwise we
    will free it along with the new "canceled" bit.
