      Looks like gevent 1.4.0 changed patch_all to return a boolean which breaks our doctest:

      >>> import gevent
      >>> from gevent import monkey
      >>> monkey.patch_all()
      True
      >>> gevent.__version__
      '1.4.0'
      

      The easy fix is to either ignore the return value which will work on all versions of gevent:

        >>> _ = monkey.patch_all()
      

      Or rely on gevent 1.4+:

        >>> monkey.patch_all()
        True
