In that case... the current CPU architecture is about as good as 
you're going to get. What'd help more would be semi-privileged access 
to the system MMU and a bit of an overhaul to the meta-memory system 
in general. A faster double-dereferencing mode would probably be 
reasonably useful too.

It's hard to say--since there's a level beyond which I really can't 
go now, I'm not sure what would be missing if I could go past it. 
Some of the old hands at this are probably better off discussing it, 
though I'm not sure any of the experimental and small-run hardware 
really got exploited to the point where you could draw reasonable 
conclusions about what could be improved.
