> We were reading some code with Jeffrey, and we realized that the
> SplitLogWorker's internal task loop is weird. It does {{ls}} every second and
> sleeps, but have another mechanism to learn about new tasks, but does not
> make affective use of the zk notification.
> I have a simple patch which might improve this area.
