Hmm, how do you mean this?
The dragonball processor has some fairly strict limits on the hardware
memory protection it provides. It only has one protected address space,
and that must appear on certain boundaries.
Even using tricks like mapping the same chip to different address spaces,
there just isn't enough fine granularity allowed to make a given memory
manager chunk writable while protecting everything else. At least, not
with the dragonball.
