    'Interrupted system call' error when running unit tests
    
    Huh. Not entirely sure what's up but when I run unit tests it fails with...
    
      Traceback (most recent call last):
        File "./run_tests.py", line 451, in <module>
          main()
        File "./run_tests.py", line 324, in main
          task.join()
        File "/home/atagar/Desktop/stem/test/task.py", line 218, in join
          self.result = self._background_pipe.recv()
      IOError: [Errno 4] Interrupted system call
    
    I suspect this is related to the unit tests finishing before the static tests
    do but not quite sure. Quick search seems to indicate it may be a python bug...
