> When CellChunkMap is created it allocates a special index chunk (or chunks) 
> where array of cell-representations is stored. When the number of 
> cell-representations is small, it is preferable to allocate a chunk smaller 
> than a default value which is 2MB.
> On the other hand, those "non-standard size" chunks can not be used in pool. 
> On-demand allocations in off-heap are costly. So this JIRA is about to 
> investigate the trade of between memory usage and the final performance.
