New submission from STINNER Victor <vstin...@redhat.com>:
I'm not sure that it's a good practice to rewrite .pyc files of the stdlib while tests are run in parallel. Maybe the test should copy all .py files of the stdlib into a temporary directory and work there, to not impact other tests run in parallel.
