Let me rephase the question:
I believe that if a multiprocessor used the full freedom allowed by
the Alpha specification, that something like what I described would
However, it isn't clear if it would be required on any existing
multiprocessor. The spec may have a lot of headroom.
It may be required that concepts such as "fresh memory" get
incorporated into the specification, implementation and programming
model of future systems.
