[Python-Dev] Caching function pointers in type objects

In CPython, is it safe to cache function pointers that are in type objects?

For example, if I know that some_type->tp_richcompare is non-NULL, and I
call it (which may execute arbitrary user code), can I assume that
some_type->tp_richcompare is still non-NULL?
