Description

Nasty & hacky patch on top of the 0.96 to get some feedback on adding this third party.
I ran a test doing "gets" on an empty region.
With the current implementation, we're spending time in the LinkedBlockingQueue#put. I was able to do 150K operations per second.

Using the disruptor allowed me to go to 190 ops/s, i.e. a little be more than a 25% improvement.

Likely there are other improvements in this class as well.
