Comment (by teor):

 The code is great - it's well-structured and a joy to read.

 But I wonder about the code copied from the base OR code:
 * have the changes to the OR code in 0.2.8 also been made in the copied
 code? (T7)
 (I wonder if this could be causing subtle breakage. But I have no evidence
 either way.)

 OK, now I'm done reading, time to debug:

 Once this patch is applied, chutney clients never download a microdesc
 consensus, even though the authorities have one. (But this works ok in
 maint-0.2.8.) I need to look into the code that's executed when a client
 asks an authority for a consensus for the first time. And I need to look
 at the code that this patch adds to existing tor OR code.
