    Research direction

    Start with the uploaded reproducer, is_alive_method.py, and inspect the multiprocessing is_alive() behavior it exercises between child processes. The issue does not specify the expected result or name CPython source files or tests, so establish the failure and expected behavior before identifying the relevant implementation and regression coverage.
