PyMem_Resize is defined as follows:

#define PyMem_Resize(p, type, n) \
	( (p) = (type *) PyMem_Realloc((p), (n) * sizeof(type)) )

The docs for PyMem_Resize don't specify that it modifies p. I suggest adding the following sentence:

"On return, p will point to the new memory area, or NULL in the event of failure."
