Bug report

The following code paths should probably returns some sort of exception status (possibly _PyStatus_NO_MEMORY()).

Note that PyInterpreterState_New() currently never returns NULL -- it calls Py_FatalError() instead -- but we should probably still handle that case as well.

_PyThreadState_New can return NULL when out of memory.
