Some FS implementations rely on it for sane performance (as in performance 
isn't just slow but orders of magnitude slow because they rely on ability 
to instantly read back what was written) so we'll have to support it. But 
I'm sure it would be possible to have a "null" layer to make it optional.

And similarly there's write buffering.
