Well, yes. The fact that pretty much all serious high-performance
designs these days _are_ OoO basically means that my brilliant idea is
DoA.

Of course, instead of replacing 1 full-ISA thread with 4 light-ISA
threads, one could  use a different number, based on what is optimum
for a given implementation. But that ratio would now vary from one
chip to another, being model-dependent.

So it's not *totally* destroyed, but this is still a major blow.
