Lars Hofhansl commented on HBASE-9754:
--------------------------------------

I meant that say that instead of a boolean, we can set if the passed readPt to 
MAX_LONG when the above condition is true, and then avoid the MVCC check as 
before when readPt==MAX_LONG. Would safe a parameter and also make sense 
(IMHO). Not important, though.

> Consider eliminating threadlocals from MVCC code

> 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.
