David, i would like to see this picked back up if possible. Is there a
way that i can help?
In particular, I would like to see the error signalling and semantics be
more clearly and explicitly defined, so that (for example) when a
keyserver has a problem the user agents (e.g. client tools like gpg
--refresh) have a clear way to distinguish between cases like:
0) "I have no key material matching this name/keyid at all"
1) "I have too many keys that match this search to bother you with an
insanely long list"
You /must/ mean documenting how those two are already implemented?
X-HKP-Results-Count: number of matching keys
Content-Length: number of bytes in resulting keys

2) "something is broken in my database, and I'm confused"
Could you /maybe just possibly/ tie this down to something like a real error
condition instead of something so ambiguous? Taking a look at lines 245-307
of wserver.ml may be helpful.
