[issue26461] PyInterpreterState_Head(), PyThreadState_Next() etc can't be sanely used

[Maciej Fijalkowski]

New submission from Maciej Fijalkowski:

All the internal uses of this API guard everything with HEAD_LOCK/HEAD_UNLOCK that's not exposed. It's not safe to traverse the whole API without holding those locks and those locks are static and module local
