I am curious about the hypervisor layer.

I can guess that it's an attempt to abstract away low level hardware
changes, a sort of software version of CPU microcode.

Or maybe it's a Transmeta kind of thing with dynamic recompilation into
a quickly evolving VLIW instruction set.

But what's the real reason?
