---------------------------------------

I think maybe the range boundary schema would be changed with this new patch.

old: [row10, row20) [row20, row30) [row30, ...)

changed to:

new:  (..., row20] (row20, row30] (row30, row40]


> If multiple of same key in an hfile and they span blocks, may miss the 
> earlier keys on a lookup
