pylint/2.15.8: python/3.11.1: debian: tests/test_check_parallel.py tests fail/hang indefinitely

Bug description

Running tests with python3.11, makes some tests/test_check_parallel.py either fail or hang indefinitely:

I: pybuild base:240: cd /build/pylint-2.15.8/.pybuild/cpython3_3.11/build; python3.11 -m pytest -vvvv -k 'not test_pkginfo and not test_do_not_import_files_from_local_directory and not test_import_plugin_from_local_directory_if_pythonpath_cwd and not test_can_list_directo
ries_without_dunder_init and not test_fail_on_exit_code and not test__test_environ_pythonpath_no_arg'

the last had to be killed

the same code, ran with python 3.10 works fine:

I think we saw this issue as well. Have you updated dill as well?

I didnt, since i didnt see any update to pyproject.toml suggesting i should. i tried with dill/0.3.6 and tests seem to work, so i've opened #7918 to address it
