No. Think about it: Where are those extra 8 bytes coming from? A
file is a contiguous piece of data, you can't insert into it randomly,
it has to be reallocated. (if you wanted to get really technically, it
could potentially be possible to create a small piece and jumping
around using i nodes, but thats way beyond the scope of our discussion)
