Comment:

 To clarify:

 We're talking about HS **clients** caching negative responses from HSDir,
 to reduce the impact of repeated requests. Is that correct?

 This description confuses me, because a client doesn't need to worry about
 memory exhaustion. It will only get as many negative cache entries as it
 asks for. On the other hand, if this is about HSDirs, I don't see how a
 negative cache would be any different from what they do now.

 Assuming we are talking about clients, it's misleading to say that this is
 a caching change. If clients keep negative responses from HSDirs longer,
 we are changing behavior significantly.
