Comment (by dgoulet):

 Replying to [comment:18 asn]:
 > Approach seems reasonable but I'm not sure whether it addresses the root
 issue which is that the service has an intro circuit open to an intro
 point which it does not respond to (the client connects fine if it fetches
 a new HS desc). Do you think that's because of the small 2 second timeout,
 or could it be another bug?

 Hmmm... I'm not seeing that in the logs. The intro point is fine and does
 relay the INTRO cell to the service, then the client gets the ACK from the
 intro point and wait on the RP.

 The issue seems that the service does NOT go to the RP and that ultimately
 makes the RP circuit *client* side to timeout *but* quite fast (2sec).
