the tracer can be killed by oom due some other random app in the machine, plus SIGCHLD may confuse the tracer, then it needs to know about arch details again (like the bitmap), and the whole ptrace infastructure is a lot more complicate and in turn less secure. syscall performance is the last worry (at least for my usage). - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
