 > We could get a NACK response from the intro point, meaning "the hidden
 service you asked me to introduce you to didn't have an intro circuit open
 to me, sorry".

 For added fun, the NACK comes in the form of an
 RELAY_COMMAND_INTRODUCE_ACK cell that has non-zero length. From the
 control port you can tell because you get

 where it used to be in OLD_HS_STATE=HSCI_INTRO_SENT but now it's in
 HS_STATE=HSCI_CONNECTING. That's because we just extend that circuit one
 more hop and try introducing again. But if that circuit already has too
 many hops, you instead just see a direct transition from HSCI_CONNECTING
 to CLOSED:

 I wonder if we want to add an explicit CIRC_MINOR event for the nack case?
