@Ed, can you elaborate a little on your reasoning? (Not doubting it; just curious.) Is it that the interruptibility provides a significant improvement over MVCL? Or the support for lengths greater than 16M? Or ... ?
When I asked Dr. Shum about move strategies he seemed to indicate that for data that was already or would soon anyway be in cache an MVC loop was generally faster than MVCL. (I did not ask about MVCLE at the time; not sure why. He did not suggest it.)

We've switched almost exclusively to MVCLE except for short, fixed-length moves.
