Comment (by asn):

 Replying to [comment:14 cypherpunks]:
 > Why it counts already_received_introduce1 if NACK only will be sent?
 Look at code of client, if all IP expired after received NACK, it keeps
 circuit alive and going to refetch the service descriptor to reuse intro
 circuit again next time for data from new descriptor for a same hs or
 another?

 hey, please see  branch from comment:9 . In that one we don't send a NAK,
 we just shut down the circuit. Does your comment still apply there?
