I personally think that Aggregators are somewhat complex. If we use
the barrier sync for Aggregators, two times number of original
supersteps is needed and vertex messages need to be sent to S + 2. To
avoid meaningless add and poll operations, we currently uses the
persistent queue. In fact, I have no idea at this moment.
