=) I want your box. Even on my Athlon box with lots of ram, a kernel compile
is definately cpu bound. I'll give you that disk access adds too much
"noise" for benchmarking. A "find . -exec cat {} >/dev/null \;" in the build
tree speeds things greatly, but then I have 512M ram. Building a test
framework around a kernel untar then build isn't that hard. (Even I can do
it...that's saying something.)

That said, this tread seems to be heading now where fast. Wouldn't it just
be nice of woody+1 could be rebuilt using tools? Software shouldn't need
hand holding.
