------------------------------
Hi [~lhofhansl] and [[email protected]],
Just would like to check is it ready now to commit this to 0.94? Or any work
left to be done? I'm considering backport HBASE-10191(although still not commit
to trunk, but seems will be in a short time) to 0.94 and observing some code
gap there w/o this patch. Thanks. :-)

> 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.
