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
packets again...

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.
