 Proposal 205 discusses a proposal for making per-circuit DNS caches, but
 closes by suggesting that instead, client-side DNS cacheing simply be
 disabled.

 This is necessary for avoiding some nasty linkability enabled by IPv6, and
 is probably a good idea for IPv4 users too.

 Rather than just turn it off, I've written a branch to make it a set of
 per-client-port options, in case there's some really important reason it's
 needed.
