Franco, you need to look at the line above that check:
PyThreadState *check = PyGILState_GetThisThreadState();
if (check && check->interp == newts->interp && check != newts)
Py_FatalError("Invalid thread state for this thread");
PyGILState_GetThisThreadState returns the original tstate *for that
thread*. What it's asserting is that, if there's a second tstate *in
that thread*, it must be in a different subinterpreter.
It doesn't prevent your second and third tstate from sharing the same
subinterpreter, but it probably should, as this check implies it's an
invariant.
