All BCMs that need updating are queued in the pre_aggregate/aggregate phase. The first set() commits all queued BCMs and subsequent set() calls short-circuit without committing anything. Since the floor BW isn't set in sum_avg/max_peak until set(), then some BCMs are committed before their associated nodes reflect the floor. Set the floor as each node is being aggregated. This ensures that all all relevant floors are set before the BCMs are committed.
