Comment:

 We should disable support for negotiating SSL v3.  Fortunately, Tor
 doesn't do the downgrade-on-fail dance, and Tor doesn't retransmit the
 same secrets in multiple TLS sessions (thus severely limiting the
 usefulness of a padding oracle attack against Tor's SSL), but thanks to
 POODLE, the time has come to drop SSL v3.
