I think this will go a long way to solve the federation delay problems we're seeing on b.s. I'm not sure at what point adding more queues will create more problems than it solves, but I do think in this case the queues are out of balance and moving broadcasts (which are the most common type of `medium_priority` task at the moment) to their own queue will be an improvement.
