Comment (by teor):

 Replying to [comment:19 asn]:
 > I added some comment to the PR but I feel like I don't know enough about
 the conn/circuit subsystem to be able to review this effectively, given
 its reachability conseuqences in case of bug. Perhaps I can pass this to
 someone else (like Nick or Tim) next week?

 I can do the review. I wrote the code that this function is based on.
