 sbws integration tests are failing because tor does not start anymore in
 Travis.
 When sbws try to launch it itself, the error is:
 {{{
     def timeout_handler(signum, frame):
 >     raise OSError('reached a %i second timeout without success' %
 timeout)
 E     OSError: reached a 90 second timeout without success
 }}}
 https://travis-ci.org/juga0/sbws/jobs/461879325#L1480
 When wait.py try to connect to the Tor test network, the error is:
 {{{
   File "/home/travis/build/torproject/sbws/.tox/integration/lib/python3.6
 /site-packages/stem/socket.py", line 525, in _make_socket
     control_socket.connect((self.address, self.port))
 ConnectionRefusedError: [Errno 111] Connection refused
 }}}

 I've tried to solve it in branch
 https://github.com/juga0/sbws/tree/travis_tor unsuccessfully. Not sure why
 this started to fail today.
