I call crapola. Modern _modern_ systems may have _some_ of the device drivers
running on seperate CPUs but they're still running in kernel mode.

A runaway device driver means you're toast.

Now, a very very busy device, thats a seperate story. Having one CPU
handle all of your disk/network IO and the second CPU handle all of your
processes may alleviate some of the pain. May. There's more to it than
just offloading stuff. If your processes are all _depending_ on IO to
occur then you may end up with random crappy starvation situations.

This has nothing to do with NANOG. Lets talk about DCEF bugs or something.
