Some minor changes to virtual memory handling
+ Should start to think about how virtual memory should be handled
efficiently, I'm sort of flailing around and not actually doing
anything beneficial. The mapping system I've so far implemented
_works_, but it's not good and I'm not happy with it. I might come
back and fix/improve it, but I think I'll go ahead and do other things for
a while, might give me a better overhead view of what the virtual
memory system should do.
+ TODO: should probably document the memory layout I'm going with at the
moment.
