> We ran into a problem at Facebook where the updateMinSlots loop in the
> scheduler was repeating infinitely. This might happen if, due to rounding, we
> are unable to assign the last few slots in a pool. This patch adds a break
> statement to ensure that the loop exists if it hasn't managed to assign any
> slots.
