EVOLVING ANSWER

It appears that Node 9.0.0 supports SharedArrayBuffer which can be found on MDN at: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/SharedArrayBuffer

and atomics: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Atomics/store

This was added to Node.js in v9.0.0: http://node.green/#ES2017-features-shared-memory-and-atomics-SharedArrayBuffer

I will continue to document everything I learn on this for others who are interested in utilizing this in Node.js.
