Cool.  Maybe Sherry can comment on the question whether it's possible
for a large-scale-memcpy to not take a hit on filling a cache line
that wasn't previously in cache?

I looked a bit at the Linux code that's being used here, but it's all
x86_64 assembler which is something I've never studied :-(.
