test_multiprocessing_forkserver.py, test_multiprocessing_fork.py and test_multiprocessing_spawn.py gives tracebacks

Bug report

During build RPM for python3.11rc1 I've found tracebacks for tests from test suite test_multiprocessing_forkserver.py, test_multiprocessing_fork.py, and test_multiprocessing_spawn.py :

[root@xxx test]# python3.11 test_multiprocessing_forkserver.py

I suppose, that tracebacks are not ok during test. Or close the bug, if it normal.
Some KeyError are present in https://github.com/python/cpython/pull/95396.

Your environment

Python 3.11.0rc1 (main, Aug 13 2022, 18:23:13) [GCC 9.3.1 20200408 (Red Hat 9.3.1-2)] on linux
Centos7 x86_64, python 3.11rc1

Reproduce los fallos con test_multiprocessing_forkserver.py, test_multiprocessing_fork.py y test_multiprocessing_spawn.py en el entorno Linux con Python 3.11 indicado. Lee multiprocessing/resource_tracker.py alrededor de la línea 209 y compara los casos de KeyError mencionados en el pull request 95396. Se considera terminado cuando se haya establecido si estos tracebacks son esperados y, si no lo son, se consiga que las pruebas afectadas finalicen sin ellos.
