There is a chance of split can happen after preScannerOpen and before
postScannerOpen. I think we can throw stale region boundary exception all the
cases because even when we throw NSRE we again need to open the scanner which
checks the region boundaries and throw the stale region boundary exception any
way. Will check it once.
