Blame the Python 2.7 developers, those suckers deprecated the PyCObject.
Grrr... I didn't see the point, myself, I'm tempted to deprecate 2.7 just to
get even. There are some routines in the numpy/core/src includes that you
might want to copy, they will allow you to use a common interface for
PyCObject and PyCapsule if you need to do that.
