Comment (by teor):

 We can only remove the retry limit if we are sure exponential backoff
 works.
 (There is still a global retry limit of 255 for every individual directory
 document.)

 Why not work out the actual number of retries we need, and increase it to
 that?

 (I would guess that we shouldn't retry a single md more than 16 or 20
 times, but that's just a guess.)

 Or, let's set the limit lower (say 6?) and try an authority when we reach
 it, then stop.
