​It also preferentially schedules "new" queues, relative to queues that
have a standing queue.  So short transactions such as dchp, ra, short RPC
transactions, VOIP, etc fly through the router relative to bulk TCP flows.

This algorithm does really wonderful things for any flow that is a "good
citizen" by pacing their traffic at their share of available bandwidth,
rather than bursting their traffic.  For the first time, there is incentive
to be a "good citizen" in your behavior.
