A slightly tricky question is what happens if a PyObject survives longer than the subinterpreter that created it. For example, in PyArrow, we allow passing a Python buffer-like object as a C++ buffer to C++ APIs. The C++ buffer could conceivably be kept around by C++ code for some time. When the C++ buffer is destroyed, Py_DECREF() is called on the Python object (I figure that we would have to switch to the future interpreter-aware PyGILState API -- when will it be available?). But what happens if the interpreter which created the Python object is already destroyed at this point?
