[issue22995] Restrict default pickleability

Barry A. Warsaw added the comment: So yeah, I guess Cython is doing something magical to boost the instance's type's basicsize, but I can't tell what from the Python prompt. It also clearly doesn't affect the un/picklability of the instance, so I think the entire check is probably misguided.
