stack commented on HBASE-12148:
-------------------------------

[~lhofhansl] Speak up if you have a problem w/ my going ahead and committing this. Agree that
two different implementations would have been the way to go until the lads showed up w/ this
nice 'trick'.... will do for both read/write (it does for sure in the problematic highly-contended
read test).
