How about that? Whether or not he is makes no difference. The context of that statement involves somebody asking why Linux does not have Zero Copy when BSD does. It seems, correctly or not, he believes the Mach people DO use Zero Copy still and given the question "(and apparently FreeBSD)" fit the answer. It's been observed here that Linus got it wrong about FreeBSD using Zero Copy even though it is (apparently from this discussion) still available. But then, it's not worth his time to actually track what FreeBSD is doing. He's concentrating on Linux, which makes sense. I'd not expect the equivalent FreeBSD people to be up on all the nuances of Linux, either. So rather than trying to make a huge flame war about this how about you just drop it. It makes no difference to the world here if Linus IS an attention whore or not. He's not HERE and he's not DEMANDING attention from anyone here. So let's just drop it rather than be drips about it. {^_^} Joanne
