(write posting, caches etc). That does of course not mean the writes
are completely free, it only means the slowdown is (much) less than 100%.

how about "it's not noticeable on a $50 CPU right now"? :^)
[ note that I cheated a bit - the stock kernel 686 routines lose ~30%
while copying. Will post a patch soon. ]
