Comment:

 A bunch of fingerprints (up to 30 in the case that triggered the ticket).
 But the typical case is 1-5.

 I'm not sure about the consensus / descriptor tradeoff.
 If the relay is down right now, then it won't be in the consensus, but its
 descriptor might be in some directory mirrors' caches.
 (But it does cause a bit of a delay in finding out that it's down.)
 I think this is ok, because our final checks make sure the relay is up.

 I'll fix the warning message (s/current consensus/recent descriptors/) and
 update the branch with this patch.
