title: Bees with Machine Guns syntax error involving paramiko. (self._close(async=True))
body: <p>I'm trying to set up Bees with Machine Guns and noticed that regardless of the command for the bees I'm getting a syntax error inside the paramiko library:</p>
  
  <pre><code>File "/usr/local/lib/python3.7/site-packages/paramiko/sftp_file.py", line 66
  self._close(async=True)
                  ^
  SyntaxError: invalid syntax
  </code></pre>
  
  <p>Thoughts on how to handle this?/how to get Bees with Machine Guns running? I was looking at <a href="https://gist.github.com/mattheworiordan/1892979" rel="nofollow noreferrer">https://gist.github.com/mattheworiordan/1892979</a> but I don't think thats for the same issue.</p>
