That's going to take some time to digest. Looks interesting, though.

Well... it can sort of help, but there are some limits. Multiple 
stacks tend to solve other problems, and they're certainly useful, 
but for a CPS scheme you really need more of a linked frame system 
than a stack system, since the control information really builds up a 
tree (albeit one often with a single branch) rather than a stack.
