When we were having the discussion on the unified model during the last
working group meeting, I forgot to point out one important use case:
That is, two processes are reading/writing to different parts of the
window. This is an important model and can only be supported in unified,
not separate (because of potential cache-line false sharing).
So, basically, no we cannot remove the unified model in spite of all its
nonsense with load/store ordering.
