> In {{StoreScanner.resetScannerStack()}}, which is called on the first
> {{next()}} call after readers have been updated, we do a query matcher reset.
> Normally this is not an issue because the query matcher does not need to
> maintain state between rows. However, if doing intra-row scanning w/ the
> specified limit, we could have the query matcher reset in the middle of
> reading a row. This could lead to incorrect behavior (too many versions
> coming back, etc).
