Sure, it's not complete yet (didn't implement the CPU saving part) as I just wanted to do a experiment I did, will improve those things by v2 then. It might take some time though. Will look into the functional test thing also. > I've had a glance through it, but better review might have to wait for > until the next development cycle. Sure, that's totally okay.
