Contra M. Beusterien, I feel it is an architectural issue in as
much as it is a problem most appropriately solved by throwing
hardware at it: The obvious architectural solution seems to be for
the caller to set a use mask, for the callee to set another
use mask, and for the processor to do a save of the intersection,
with special-purpose logic. Anything like this out there?
