One thing that had come to my mind was somehow one might use
GlobalArray as a back-end and the ndarray interface as a front-end,
but so much of the ndarray code assumes that one can use pointer
arithmetic to access the data that I couldn't see a good way to make
this work. Is there a clever way of implementing a distributed array
that would allow one to re-use as much of the numpy core code as
