Comment:

 Pushed with some minor tweaks...
 https://gitweb.torproject.org/stem.git/commitdiff/74ba2e9

 However, as mentioned in the commit description there's a couple things
 I'm uncertain about...

 {{{
 However, there's still a couple mysteries...

 * When I was offline I got the following stacktrace...

 ======================================================================

 ERROR: test_extendcircuit

 ----------------------------------------------------------------------
 Traceback:
   File "/home/atagar/Desktop/stem/test/integ/control/controller.py", line
 373, in test_extendcircuit
     circ_id = controller.extend_circuit(0)
   File "/home/atagar/Desktop/stem/stem/control.py", line 1109, in
 extend_circuit
     raise stem.socket.ProtocolError("EXTENDCIRCUIT returned unexpected
 response code: %s" % response.code)
 ProtocolError: EXTENDCIRCUIT returned unexpected response code: 512
 ----------------------------------------------------------------------

   However, according to the control-spec the 512 response code is for
 "Syntax
   error in command argument". That doesn't make sense if we're failing
 because
   we lack a connection.

 * Is the 'path' argument for EXTENDCIRCUIT the circuits that we build
 through,
   or the relays to be chosen from when building a single hop? The
 EXTENDCIRCUIT
   description doesn't say, which seems to me to be a weakness in the spec.
