Oh I wasn't arguing for breaking it, just jesting. We need to keep it
working. It's amazing how well broken stuff actually work though :-)

I mean, it's architecturally broken and if we get a collision between
the cache and the NCU, the chip will crash. We just get lucky I suppose.

Anyway, I'll try a different approach tomorrow see how it goes.
