I agree, but please note that the child_reaper is not the only issue. Think about sub-thread which auto-reaps itself. I'd suggest to add the comment in do_exit() after exit_notify() to remind that the task is really dead now, it has no ->signal, it can't be seen in /proc/, we can't send a signal to it, etc. Oleg. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
