If I understand this issue correctly, perhaps the test case should be augmented to check for a cycle:
try:
main()
except RuntimeError as exc:
self.assertIsNone(exc.__cause__)
else:
self.fail("Expected RuntimeError")

I don't agree that a reference cycle counts as a release blocker. |

This cycle leads to infinite unbreakable loop in cpython c internals.
