------------------------------------------------
bq.shallowCellsToBuffer
This method in the test and the corresponding code explains what really
happens. It looks great.
So the CellBlockSerialized (I think we can have a better name) - will work only
if the MSLAB Chunk pool is ON right? If there is no MSLAB chunk pool still it
can work? I may be missing something.
Now the entire cellblock is just referred from the index creating using 3
Integers. Great.
Now in your shallowCellsToBuffer even the shallowBuffer is created with the
same 'chunkSize' as we create the deepbuffer also? Is that really needed?
How does things work when the chunkpool gets reset and initialized? Will do one
more process later this week.
