Well... perhaps you could create another PyObject (it's just a wrapper,
right?) since the old one doesn't have any outside references to it
remaining.

Note that calling __del__ only once is also how PyPy works:
http://doc.pypy.org/en/latest/cpython_differences.html#differences-related-to-garbage-collection-strategies

If there is some demand we could expose a higher-level spelling of
`_PyGC_SET_FINALIZED(self, 0)`.
