Why in the world should we encourage these queues to get big?

There is a big difference between putting memory in so the queues can get 
big as the result of transient congestion, and encouraging routers to 
operate with these big queues full!

Any control theorist will tell you that if you fill up all of the buffers 
in the network, there is no way to control it stably.   (a simple 
simulation will demonstrate it as well).

It's like trying to drive a car at high speed from the back seat with 
rubber bands tied onto the steering wheel.
