Bug report

Bug description:

There's a certain amount of Cpython-specific tests which isn't marked with acpython_only decorator.

I'm certain that CPython-specific tests should be excluded from running on any other implementation, which is advantageous for us. This ensures that when developing another Python implementation, you can selectively avoid running these specific CPython tests, which is beneficial during the testing phase. This way, you can focus on relevant tests for your implementation without unnecessary interference from CPython-specific ones.

So, my final goal is to make the whole CPython test suite runnable on other Python implementations.

I would like to send a one PR per test file which needs a fix.

CPython versions tested on:

CPython main branch
