Yeah, you probably would but the hypothesis is that you'd end up with
a bigger net developer base for the _Linux_ version. Now you might not
think that's important but I certainly do and I think Ingo does as
well. ;-)

That said, pulling 400 KLOC of code into the kernel sounds really
excessive. Would we need all that if we just do native virtualization
and no actual emulation?
