Just got the updated Spare Parts and there's a new feature called Activity/Process Management and you can choose between Aggressive and Normal(Defualt). I guess it will end tasks and manage memory more quickly. It warns you of doing this, of course. I enabled aggressive and will try to report back any findings. There's also ads now...
UPDATE: First observation, it has to keep launching Sense... deal-breaker. Back to default on that one.
