 Seems like people have started receiving this `Duplicate rendezvous cookie
 in ESTABLISH_RENDEZVOUS` warning message on their relays:
 https://lists.torproject.org/pipermail/tor-relays/2016-October/010535.html

 This might be a logic bug in tor, or it might be that Tor clients (or an
 alt implementation) is reusing the same rend point and same rend cookie
 multiple times, which simply does not work.

 (Meta: Unclear what `Points` should be in this ticket)
