Comment(by arma):

 Replying to [comment:54 Sebastian]:
 > For the refetching of descriptors, we'd need some kind of logic to check
 that we don't refetch a descriptor if the one we have looks recent and
 there are no other events that might cause us to like it now (we got a new
 consensus).

 The origin design here (back before v2 hidserv protocol existed) was "if
 you get a .onion request and you have a cached not-too-old descriptor, use
 it. if it runs out of intro points, fetch a new one. if the new one you
 fetched is equal to the old one you had cached, fail all pending .onion
 requests and stop. else goto step 1."

 So we could try reusing that same idea here -- if you do a fetch and you
 got the thing you already gave up on, give up.
