Hello @mihalicyn

def test_robust_lists():
    # Starting a process with a robust list
    pid = os.fork()
    if pid == 0:
        # Child process
        robust_list = [1, 2, 3]
        prctl(PR_SET_NAME, "child")
        set_robust_list(robust_list)
        # Wait for a signal to terminate
        signal.pause()
        os._exit(0)
    else:
        # Parent process
        prctl(PR_SET_NAME, "parent")
        # Check that the child process has a robust list
        child_list = get_robust_list(pid)
        assert child_list == [1, 2, 3]
        # Send a signal to the child process
        os.kill(pid, signal.SIGUSR1)
        os.waitpid(pid, 0)

This test case checks that the list exists using get_robust_list(), sends a signal to the child process, and waits for it to terminate. This tests several code paths related to robust lists and can be used as a starting point for additional tests.
