Thanks Lon, I understand.
And if I kill -9 (SIGKILL) the higher-numbered PID at test purpose,
is it expected to reboot or not ?

I see in code :
                case SIGCHLD:
                case SIGILL:
                case SIGFPE:
                case SIGSEGV:
                case SIGBUS:
                        setup_signal(i, SIG_DFL);
                        break;
                default:
                        setup_signal(i, signal_handler);
but can't conclude for a SIGKILL on higher-numbered PID process ...

Thanks again
