That assumes you write out full blocks.  If you flush after
every byte written you'll hit the limit a lot sooner ;)

Btw, this is also a problem with your patch, when you write
out buffers all the time your disk will spend more time seeking
all over the place (moving the disk head away from where we are
currently reading!) and you'll end up writing the same block
multiple times ...
