Someone I work with recently caused a test to start asserting in VC7's instrumented free() call, using a pydebug build. He explained the change this way:
"I switched from PyObject_New to PyObject_NEW, which according to it's documentation omits the check for type_object != 0 and consequently should run a little bit faster"
[he doesn't ever pass 0 as the typeobject]
Did he miss some other important fact about PyObject_NEW? Does the doc need to be fixed?
