> We noticed an anomaly in paged results while testing against 3.0.0-alpha1. It seems that
unbounded selects can return rows repeated at page boundaries. Furthermore, the number of
repeated rows seems to dither in count across consecutive runs of the same query.
> I also noted that this behavior only manifests on multi-node clusters.
> The attached script shows this behavior when run against 3.0.0-alpha1.
