 Replying to [ticket:12170 nickm]:
 > Does changing our opinion about a node's is_running status count as a
 change in whether we know most of the nodes in the network?  Should it?

 I think the answer is currently yes here -- if we mark a lot of relays
 down, then we might not have enough relays available to make a (good
 enough) circuit.

 The broader question I guess is whether we should be believing our local
 view over the consensus view -- traditionally they differed because
 something changed since the consensus that we saw with our own eyes, but
 we can also imagine that some relays aren't reachable from our location,
 or active attacks, or etc. That's not really quite this question though.
