No arguments from my end.

I've been attempting to get what I have in some sort of state that will:
a) compile cleanly
b) have some basic structure to work from.
c) have something in basic (read block / write block of data) working order.

Just when I find time to get point a), I rebase and am back to
cleaning up the conflicts..
Then I look over what I've done and decide that the code should not be
inflicted on anybody :)
