Good idea. Alternatively, we could make "APIs" a feature of modules:
PyModule_GetAPI, PyModule_SetAPI. We would then define

typedef struct {
	PyObject *md_dict;
        PyObject *md_api;
} PyModuleObject;

We could restrict md_api to CObjects, which, means we would not need
to change module_traverse.
