Bug description:

While working on gh-154902 for the 3.14 branch, I noticed that:

test.test_typing.GenericTests.test_parameters_deep_recursion failed on the x86_64-unknown-linux-gnu/gcc-free-threading job

Job link - https://github.com/python/cpython/actions/runs/30756488244/job/91519428824?pr=155072

FAIL: test_parameters_deep_recursion (test.test_typing.GenericTests.test_parameters_deep_recursion)

Traceback (most recent call last):

         ~~~~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AssertionError: RecursionError not raised

The test expects list[x].__parameters__ to raise RecursionError for a list
nested exceeds_recursion_limit() deep, and on this job it didn't. Every other job in
the same run passed.

I don't know the cause yet, filing so it isn't lost
