Testing
-------
Ran benchmarks against it in HBase standalone mode. Wrote test cases for all
classes, multithreaded test cases exist for the cache.
Thanks,

>
> 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.
