Yes. The solution to that is to check for huge array sizes, and use a 
different routine (using prefetching) in that case. Actually, the most 
important routine to be doing that is memcpy/ array slice assignment, 
but I'm not sure it does. I think it just does a movsd.

So I think this is still a useful case to benchmark, it's not the most 
important one, though.
