Comment(by jinmei):

 Oh, and one more thing (different topic than !NameMatch, etc).

 I suspect the current implementation is very susceptible to DoS.  I'd
 simply keep sending different queries that result in negative responses.
 They'll simply be cached and never purged.

 I suggest by default we should disable cache, and by default impose some
 finite limit on the # of cache entries.
