we just call the slab chunks blocks? or should we call them chunks everywhere
to avoid confusion with hfile blocks? although they are kinda the same :)

bq. I'm probably gonna change this to the MemCached model, where the slabs
are "pages", and blocks are "chunks". Or we can just go our own way.
We're going to call it Slabs and Blocks. Either way, easy enough change. Will
make it consistent.

> Java offers the creation of direct byte buffers which are allocated outside
> of the heap.
> They need to be manually free'd, which can be accomplished using an
> documented {{clean}} method.
> The feature will be optional. After implementing, we can benchmark for
> differences in speed and garbage collection observances.
