Description

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.
