> Allocation of Large Containers are notoriously problematic, as smaller 
> containers can more easily grab resources. 
> The proposal for this JIRA is to maintain a map of container sizes, and 
> time-to-allocation, that can be used as:
> * general insight on cluster behavior, 
> * to inform the reservation-system, and allows us to "account for delays" in 
> allocation, so that the user reservation is respected regardless the size of 
> containers requested.
