Yah. That's what triggered my personal "mmap" flag when he referenced a 2G limit, and you know the rest. > Anyway, I suppose I shouldn't have bothered responding to any of this. Sigh. Well, not when you turn around and do exactly what you just gave me hell for doing. 8-). Your point from the last post that we are all human is well taken; I think that anyone who relies on what another person says as "writ of God" is making a mistake.
