Is a flood even realistic, given expected CPU speed and pipe widths?
It seems that the bottleneck would get hit on bandwidth before starvation
effects happen.  Could a flooding attack really fill the packet queue faster
than than the code can drain it?

And given this attack, processing a hundred packets on the attacked port
before getting to an unattacked port -- there's a tradeoff there to.

Mindlessly defending the status quo even as it shifts,
