It looks like calloc-3.patch is wrong: it modify _PyObject_GC_Malloc() to fill the newly allocated buffer with zeros, but _PyObject_GC_Malloc() is not only called by PyType_GenericAlloc(): it is also used by _PyObject_GC_New() and _PyObject_GC_NewVar(). The patch is maybe a little bit slower because it writes zeros twice.

calloc.patch adds "PyObject* _PyObject_GC_Calloc(size_t);" and doesn't have this issue.
