Comment (by teor):

 And that's fair enough, we weren't expecting to have to use descriptor
 bandwidths for anything.

 Here's the simplest model we could use:
 * take the latest measurement, and scale by the descriptor bandwidth at
 the time of the measurement

 Here's a more accurate model we could use:
 * take the decaying average of the measurements, and scale by the decaying
 average of the descriptor bandwidths

 And we should probably think about:
 * how we handle zeroes (replace with 1 is a nice simple fix for a bunch of
 issues)
 * how we handle new relays (treat their old bandwidths as 1 is a nice
 simple way of rewarding stability)
