> 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)
