Comment (by nickm):

 It doesn't take the last address; it takes the first one.
 {{{
     } else if (tor_addr_family(&addr->addr) == AF_INET6) {
       if (!addr_ipv6 && conn->ipv6_traffic_ok) {
         addr_ipv6 = addr;
       }
     }
 }}}
 Note how it doesn't set addr_ipv6 unless addr_ipv6 was previously NULL.

 Will revisit other questions once the tests are done.
