I really like this, when I'm done with trying to create a JIT compiler I think I'll move on to building a mini-OS in my spare time. I'm sure this combined with this [1] will be a great course unto itself.
I would post this too, it is nice concepts, but it seems stopped, at the most important place, process managment. It would be very nice to complete it.
