Description

Brought up by vrodionov and yuzhihong@gmail.com.
Currently we use ThreadLocals to communicate the current readpoint between a RegionScanner and the Store{File}Scanner's down the stack.
Since ThreadLocals are not cheap we should consider whether it is possible to pass the readpoint through the call stack instead.
