Another piece of the kernelside puzzle is designing the VM layout for
64-bit processes. Do we want to (as ia64 does) reserve parts of the address
space for the kernel? Map shared libraries in different quadrants from
the user process? Keep data in yet another quadrant?
It's a lot of work, and I'm not sure the will is there to make it happen.
