[docs] Invalid method name in example for multiprocessing 3.2

[Viktor Lucza]

The problem was found here:
http://docs.python.org/3.2/library/multiprocessing.html#module-multiprocessing.pool

I believe one of these should be called next instead of __next__:

# Proxy type for generator objectsclass GeneratorProxy(BaseProxy):
    _exposed_ = ('next', '__next__')
    def __iter__(self):
        return self
    def __next__(self):
        return self._callmethod('next')
    def __next__(self):
        return self._callmethod('__next__')
