Why should any filesystem perform seeks better (when writing) than any 
other filesystem?

I imagine it could be true only if:

- kernel would cache a large amount of writes
- kernel would commit these writes not in a FIFO manner, but whenever it 
sees that the blocks on the underlying device are close to each other

Can ZFS do it?
