I tested to build numpy with an opaque PyThreadState. First issue, Plex gets
the current interpreter using PyThreadState.interp:
/tmp/pip-install-aq60p8w2/Cython/Cython/Plex/Scanners.c:7447:73: erreur:
déréférencement d'un pointeur du type incomplet « PyThreadState » {alias «
struct _ts »}
7447 | PY_INT64_T current_id =
PyInterpreterState_GetID(PyThreadState_Get()->interp);
We should add a PyThreadState_GetInterpreter(tstate) getter.
faulthandler_py_enable() would use it for example.
Maybe _PyInterpreterState_Get() can be used, but it's a private function. There
are also _PyThreadState_UncheckedGet() and
_PyGILState_GetInterpreterStateUnsafe() which are worse: don't check for NULL
pointers.
