> 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.
