> At present, ordering policies have the option to have an application re-ordered (for allocation and preemption) when it is allocated to or a container is recovered from the application.  Some ordering policies may also need to reorder when demand changes if that is part of the ordering comparison, this needs to be made available (and used by the fairorderingpolicy when sizebasedweight is true)
