 circuits on newnym, but reintroduce to any hidden service that we want to
 stay connected to every MaxCircuitDirtiness seconds (current default 10
 min, I think).

 circuits than for general circuits, where (unless I'm mistaken) only the
 first stream getting attached causes the circuit timestamp_dirty to get
 set.

 Yes.  See also the changes/ entry for one of my patches for #1297 --
 starting in 0.0.6, one piece of Tor expected `timestamp_dirty` to have
 even more meanings for HS-related circuits, but it didn't actually have
 that meaning.
