Comment(by atagar):

 > What kind of object does launch_tor return

 It provides a process. launch_tor() is not restricted to making a tor
 process with a control socket, and even if there is one launch_tor() won't
 know the password if HashedControlPassword was set.

 We could make a more restricted launch_tor* method that provides back a
 Controller. However, I'd rather invest our effort in making an is_local()
 check that actually works. You make a good point that it's non-trivial to
 figure out, but it would be a useful to detect for reasons other than
 TAKEOWNERSHIP. Suggestions on how to do that are welcome.

 > and how do callers obtain a Controller object from that one?

 There's a few ways. One would be...

 {{{
 tor_process = stem.process.launch_tor_with_config(
   config = {
     'ControlPort': '2778',
     'CookieAuthentication': '1',
   },
 )

 controller = Controller.from_port(control_port = 2778)
 controller.authenticate()

 # ... do some stuff...

 controller.close()
 tor_process.kill()
 }}}
