Wow, I think that ends up looking like a compiler, or at 
least the optimizing back end part of a compiler.  I worked 
a bit with a Trace Multiflow, and their optimizing back end 
was VERY slow, which I assume means it was a complex task to 
reorder all the atomic operations and pack into the long 
instruction words for best throughput.

I think it might end up looking a bit like the optimizers 
that were used on drum memory computers back in the dark ages.
