It's actually better than you thought. Using PyObject_NEW is the 1.5.2
way to spell "allocate and initialize object"; it is the rename2.h
name for NEWOBJ.

Your review shows that using PyObject_New and PyObject_Del is not
common, I'd now question that there actually is real-world code that
uses them incorrectly. So here is my theory:

If PyObject_NEW becomes malloc, and PyObject_New becomes pymalloc,
nothing would break.
