- Well. Todays major _OS_ does not have memory protection. But you

- Unfortunately this would include all old programs like Intuition, the
- Filesystems, the interrupts, old drivers.

- This basically means a completely new and incompatible OS and some kind
- of emulation for old programs. Needless to say that this will be limited
- and significantly slower for the emulated system.

- I think we can do something better...
