 INTRODUCE_ACK.

 This is normal and natural behavior btw -- once you send the
 ESTABLISH_INTRO cell to the introduction point, there's a race between
 when you get back the INTRODUCE_ACK from the intro point (saying "yes I
 sent your introduction request on to the hidden service") and when you get
 back the RENDEZVOUS2 cell (from the hidden service). I'd guess the intro
 ack comes back first more often, but it really depends on load inside the
 Tor network at that time.

 > Maybe the correct behavior in this case is that connection to the IP
 should be considered as finished when you have received either RENDEZVOUS2
 or INTRODUCE_ACK?

 Sounds plausible. I might even suggest leaving out the "do we get an ack"
 step in the case where we also (eventually) get a rendezvous2 cell, since
 they aren't ordered events. But tracking them is fine too in case we learn
 something.
