I think it is more likely to hit a dynamic equilibrium: the % of packets
dropped increases proportionately as the queue gets fuller.
Otherwise I suspect it will become bursty: queue goes over 50% and is
increasing, we start dropping packets, the queue starts to shrink, we start
accepting packets for a while, the queue starts to grow, we start dropping
OTOH, we wouldn't get the full benefit of this unless the NASes implement
exponential backoff. If they just resend packets every 3 seconds, say, then
an overload situation will remain an overload situation anyway.
