I was thinking that the CPU L1/L2 cache will have much the same effect, but 
I suppose on the type of systems we're talking about, there's not going to be 
a usefully large CPU cache. Shame; it seemed like quite a nice idea. 

It'd be nice to retain the option of doing it for those systems where it makes
sense - and I think the way you're doing it should allow that. So we can look 
into it later if we want to.
