I think we need to change this decision. PyCObject is still available on
Python 2.7, and will only raise a PendingDeprecationWarning, which does
not show up by default. I believe the Python devs reversed the full
deprecation before the final 2.7 release.
So I think we should just stick with PyCObject on 2.x, as we have done so
far. I'll just bump the version checks so that PyCapsule is used only on
I'll commit this to Numpy SVN soon.
