 > I'm assuming that the part about `just upload your server descriptor
 immediately` is moot with `PublishServerDescriptor 0`, although that's not
 quite clear from the manual. So I'm assuming the combo means `don’t do
 self-reachability testing`, which //does// sound quite appropriate for a
 local test relay, although I'm not sure what reachability testing looks
 like. (Just thought I'd ping you for confirmation and a potential learning
 opportunity for me.)

 I think it's a safe assumption for me that this is a good change :).
 Without knowing more about reachability testing, I'd imagine it
 constitutes some sort of outbound communication to check whether our
 ORPort is reachable from another relay. Since we explicitly don't want to
 publish info to contact our relay, turning off this sort of behavior just
 makes sense to me (if it //is// as I'm guessing it to be).

 I've pushed another commit to the github branch:
 `git at github.com:dmr-x/stem.git` branch `25631-integ-torrc` commit
 `37d11c67773361bbebf521691d57468e6ea51d32`
