Jason, I both like and respect you, but you are wrong here. You just flat out don't know what you're talking about. This has nothing to do with the choice of "a general purpose CPU", it is a result of a specific architecture within the CPU chosen. There is a real difference here. You're talking like this was a negligent choice made in total disregard of known facts by Cisco, and that just isn't so. And deep down, you *know* that's true too (although it removes your premise and robs you of some wonderful /rants). Sure, Cisco chose a poor architecture, and we know that today. That doesn't mean that this was understood in the setting under which the decisions were made. This goes back a loooonnnnngggggg way. The fact is, IOS is pretty well put together, and considering it's running on an obviously deficient platform and has withstood all comers up to now is pretty amazing. They fucked up. They'll have to fix it then. But thats not the same as the gross negligence they're being accused of. <FullDisclosure> I am not a Cisco fan, and Jason can attest to that. Also, I own no stock or have any other interest in Cisco.</FullDisclosure> -- Yours, J.A.
