> Allocations can be preempted and are marked as being preempted already.
> The {{PreemptionContext.filterAllocations()}} call does not check if the allocation is already being preempted. It might thus consider it again as being pre-emptable during a second check.
> We should exclude allocations already being preempted from the list of victims.
> The impact should be limited at this point as we cannot have two reservations trigger preemption at the moment.
