        I dunno. Can't you not send any response for a time (15s?)
        while you wait to see if priority port traffic is still
        occurring? If a firewall can NAT, you can keep track of
        which TCP connections are on the poop list.

        UDP isn't acknowledged, TCP requires an ACK or the like.

        Saturation for "a moment" is not a problem in the overall picture.
