This may lead to duplicate ids: pid may be reused and time may be shifted to give exactly the same start_time as it was used with this pid earlier. Simple increment will work fine. Ok, as far as no one else commented at my idea, I assume it is not completely stupid and will try to implement this :) -- // cronfy _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
