> as part of adding unit tests to TestWindowFrame, I added a debug option to MSorter to
force the batches passed downstream to be of a specific size. This was supposed to help test
edge cases involving multiple data batches while controlling precisely when a partition and/or
window frame ends in a batch.
> Turns out the change to MSorter was incomplete and all cases end up processing one single
big batch of data.
> The purpose of this JIRA issue is to fix this, add some check to detect when the batches
are no longer split correctly and make sure all unit tests are passing.
