    Research direction

    Start with the reproducible example in test.py and run it to observe the exit result when multiprocessing.Process receives SIGINT. Trace the relevant interpreter-core and multiprocessing behavior, then verify that the process exits with the expected result code and that the regression is covered by a test.
