> This is based on a discussion over [~anastas]'s patch. The MemstoreSnapshot
> uses a KeyValueScanner which actually seems redundant considering we already
> have a SegmentScanner. The idea is that the snapshot scanner should be a
> simple iterator type of scanner but it lacks the capability to do the
> reference counting on that segment that is now used in snapshot. With
> snapshot having mulitple segments in the latest impl it is better we hold on
> to the segment by doing ref counting.
