Research direction
Start by running the attached bug_demo.py to reproduce the reported race condition, then inspect Python's multiprocessing managed Queue implementation and its tests. The issue does not specify the expected behavior or affected source file, so the completion criteria would need to be agreed before a fix and regression test can be defined.
