Comment(by arma):

 Profiling fast Tor relays in the past showed that they spent 5-10% of
 their cpu time refilling buckets.

 If we refill buckets 100 times as often, will we spend 90% of our cpu time
 refilling buckets?

 Also, are we removing any realistic chance that we would flush more than
 one cell at once? If MTUs are often 1500, sending a second cell could be
 much cheaper than the earlier analysis implies.

 That's not to mean we shouldn't make a change like this. But it would be
 great to better understand what results we expect to see, so we can check
 to make sure that we actually see them.
