// This is a not very elegant fix for a problem that occurs with the
// free-threaded build of Python. If this is called when the interpreter
// has already been finalized, the thread-state can be null. Unlike the
// GIL-enabled build, Py_DECREF() requires a valid thread-state. This
// causes a memory leak, rather than crash, which seems preferable.
