Comment (by nickm):

 I think one of the changes I suggested in #9969 would work well for this:
 do not have more than N requests of the same type in flight to the same
 directory guard at the same time.  So suppose we have 3 directory guards,
 and request our microdescriptors in 18 chunks.  Under the current system,
 1/3 of our requests will be made to the borken guard, and will have to
 time out.  Under the suggestion I made, if N=2, only 2 requests will be
 made to the broken guard.  As the other requests are answered by the other
 guards, we'll send more requests to them.  So only 1/9 of the total
 requests would time out, and we could probably bootstrap.
