As Victor said, the `time.sleep(1.0)` might lead to Heisen failures. I am not sure how to write proper strong synchronization in this case but we could instead go for something intermediate such as the following pattern:


        ...
        p.terminate()
        p.wait()
        for i in range(60):
            try:
                shared_memory.SharedMemory(name, create=False)
            except FileNotFoundError:
                # the OS successfully collected the segment as expected
                break

            time.sleep(1.0)  # wait for the OS to collect the segment

         else:
             raise AssertionError(f"Failed to collect shared_memory segment {name}")


What do you think?
