Comment (by dgoulet):

 Replying to [comment:11 arma]:
 > 10) Is there any reason to keep an intro1 circuit open once it's
 received its intro1 cell? I notice we're closing it on nak. Why not close
 it on ack too? Is there anything that it can do after it gets its intro1
 cell that we want to allow?

 Very good question! Current code doesn't close the client circuit after a
 ACK... I think it might be because before we used to allow multiple
 INTRODUCE1 cell so we let the client close it but it's not the case
 anymore so I believe closing it here is good thing to do. Thoughts?
