    Stacktrace when queue module is present
    
    When running with the python 2.x if you have the queue module we use
    io.StringIO rather than StringIO.StringIO. This causes two of our Controller's
    methods to fail with...
    
      Traceback (most recent call last):
        File "circuits.py", line 7, in <module>
          for circ in sorted(controller.get_circuits()):
        File "/usr/lib/python2.7/site-packages/stem/control.py", line 455, in wrapped
          return func(self, *args, **kwargs)
        File "/usr/lib/python2.7/site-packages/stem/control.py", line 3284, in get_circuits
          circ_message = stem.socket.recv_message(StringIO('650 CIRC ' + circ + '\r\n'))
      TypeError: initial_value must be unicode or None, not str
    
    Thanks to mancha for catching this!
