> Doing a doMiniBatchMutate, we calculate the set of families that the WALEdit Cells belong to up front but down after the RingBuffer when we make an FSWALEdit, we spin through all the Cells again to figure the set of families in a particularly painful way. Just pass the calculated family set in the WALEdit.
