How would this tricks influence performance on machines with
a high CPU/bandwidth ratio and/or simple caches (ie. PPC,
some MIPSen, ARM and some Alphas)?
I guess that on a fast CPU with less memory bandwidth the
effect will be more noticable... And since it looks like
some people have already coded it, there shouldn't be any
harm in putting it inside the kernel ;)
