 If we revert the exponential backoff code as our solution to #20499, we
 will want to tweak the final times on some of these schedules, to achieve
 Roger's goal of "never have a relay stop trying entirely".

 If we don't, we will want to adjust the initial time as well.

 So I think my comment was a bit hasty - it's only the middle times that
 don't matter, and only if we keep exponential backoff.
