There's a fair chance that the dSetZeros overhead will just move 
elsewhere, because it has the nice property of gulping the data 
you're going to overwrite into L2 cache (and L1, if it's a very 
small piece of data). That cost would have to be paid anyway when 
you want to write to the data. Doing it all at once may actually 
be more efficient (if you don't want to include prefetching in 
the inner loops).

Cheers,
