 Replying to [comment:13 asn]:
 > Hello teor, what can I do here to help? What's the current status here?
 I can spend a few hours this week on this ticket.

 The code works and has been tested using chutney.

 It doesn't behave correctly when
 RendezvousSingleOnionServiceNonAnonymousServer Is changed at runtime
 (using torrc and a HUP, or over the control port). The current code
 attempts to re-use introduction points and introduction point circuits
 after a HUP. But if the value of
 RendezvousSingleOnionServiceNonAnonymousServer has changed, the circuits
 are the wrong length. Tor should close the circuits and discard the intro
 points (this needs to be coded), then post a fresh descriptor (this likely
 already happens anyway after a config change).

 There aren't any specific unit tests, but any existing unit tests pass.
