Research direction
Start with the uploaded reproduction, race2.py, and run it against the multiprocessing Manager server during finalization to observe the intermittent BrokenPipeError. Trace the Manager server's finalization path and identify the conditions that close or use the pipe; done means the reproduction no longer reports a broken pipe during finalization.
