> The idea is that most of the logic of calling Python actually has nothing to do with RDD (it is really just communicating with a socket -- there is nothing distributed about it), and it is only currently depending on RDD because it was written this way.
> If we extract that functionality out, we can apply it to area of the code that doesn't depend on RDDs, and also make it easier to test.
