Conceptually, we take an exponentially weighted mean average of the number
of cells a circuit has sent, and allow active circuits (those with cells to
relay) to send cells in order of their exponentially-weighted mean average
(EWMA) cell count. [That is, a cell sent N seconds ago 'counts' F^N times
as much as a cell sent now, for 0<F<1.0.]

F^N times as much as a cell sent now, for 0<F<1.0, and we favor the
circuit that has sent the fewest cells]
If 'double' had infinite precision, we could do this simply by counting a
cell sent at startup as having weight 1.0, and a cell sent N seconds later
