      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
