--------------------------------------------------------------

Looking at the patch it seems this was wrong for a while.
Will this throw off any other recent selection improvements? Some of the Facebook folks should
look at this.
[~kannanm], [~mikhail], [~nspiegelberg], [~karthik.ranga], does any of you have any comments?

> Currently compaction selection is not sorting based on size.  This causes selection to
choose larger files to re-write than are needed when bulk loads are involved.
