Apparently, "what's up" is that I will need to implement a third
method in my ndarray subclass -- namely, __reduce__.

I'm burned out for tonight, I'll attempt to grasp what __reduce__ does
tomorrow.

Again, I'm going to point out that, given the extent that
multiprocessing depends upon pickling, pickling should be made
easier.  This is Python, for goodness' sake!  I'm still surprised at
the hoops I've got to jump through.
