   This would be true if the time between packet arrivals was constant.
   When the inter-arrival time is variable (or the size of the packets is
   variable, or both), a queue will form even if the average input rate
   is lower than the average output rate
   
Sigh.  Note that I said *max* input rate, not avg.  This bounds the
smallest allowable inter-arrival time.

This whole subject is both a minor point about an artificial example; I'm
glad to continue discussing it, but no need to clutter up e2e.  If other
people want to talk to me about this, or correct me, or whatever, remove
e2e/ecn.  Thanks.
