    Make exit_used.py compatible with asyncio
    
    Honestly this is probably somewhat a step backward because if I return to Stem
    I plan to substantially revert the asyncio migration, but for now simply fixing
    the script. With the current codebase it fails with...
    
      % python exit_used.py
      Tracking requests for tor exits. Press 'enter' to end.
    
      stem/stem/control.py:4004: RuntimeWarning: coroutine 'Controller.get_circuit' was never awaited
        log.warn('Event listener raised an uncaught exception (%s): %s' % (exc, event))
