Good point :o) I was thinking: I could split the PIDs up in 2...16383 and 16384-32767 and then switch between them when a process ends? nah, that doesn't help it. hmmm. I think random increments (instead of last_pid+1) would be the best thing to do then? - 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/
