updated for version 7.3.998
Problem:    Python: garbage collection issues.
Solution:   Fix the GC issues: Use proper DESTRUCTOR_FINISH: avoids negative
            refcounts, use PyObject_GC_* for objects with tp_traverse and
            tp_clear, add RangeTraverse and RangeClear, use Py_XDECREF in some
            places. (ZyX)
