 When tor first bootstraps, it launches two requests for authority
 certificates:
 * one is the hinted request that goes to the directory it downloaded the
 consensus from (ticket?)
 * one is a scheduled request that goes to a random directory

 We should delay the first scheduled request slightly (5s?) to allow the
 first request to complete.
 This might be as easy as changing the first number in the authority
 certificate schedule from 0 to 5.

 I thought we avoided fetching certificates if another fetch was in
 progress: clearly that doesn't happen, and maybe we don't want it to,
 because we don't want to wait a whole 10 seconds for it to timeout.
