Interesting point -- I assume we're having this conversation because tor
launcher decided to leave it to tor how to shut down. Does that mean you
recommend that Tor Launcher send Tor some other signal before closing the
connection? This seems to be one of those cases where if we're going to
recommend that every controller do some behavior, it's better to have it
happen on the Tor side.
Do we know of any cases where, once you've set takeownership, for a Tor
that's a relay, you'll want to let the Tor persist a while more even
though the controller has vanished?
I would think that if the controller wants to do something fancy like a
controlled shutdown of Tor, it shouldn't close its control port until it's
done doing the fancy thing.
So to be clear, I think we'll be happier here just changing
lost_owning_controller() so it calls tor_cleanup and exits.
