Comment (by asn):

 More questions for future log digging:

 - Does the attacker send multiple `INTRODUCE1` cells on a single circuit?
 So basically he can cause N rendezvous with a single circuit? We should
 look on whether this is possible and maybe fix it.

 - In the log of comment:8, we received about 14k `INTRODUCE2` cells, which
 means that we tried to establish that many rendezvous circuits. We also
 did many relaunches of rendezvous circuits because of failures. Two
 important questions here: Why did those rend circs fail, is it because of
 the guard? How many circuit relaunches happened in total?
