I got this in Cython's continuous integration server after this change:


Traceback (most recent call last):
   File "runtests.py", line 19, in <module>
     import cPickle as pickle
TypeError: PyCObject_AsVoidPtr with non-C-object


Although this looks like an internal problem in CPython, I'm certainly 
against any backwards incompatible changes of this size in the 2.x series.
