Yes the downside of the this is that threads once created aren't closed until shutdown.
Made a change to add a keepAliveTime for idle threads so this would no longer be the case. I was missing the allowCoreThreadTimeOut() method in testing which allows the timer to be applied.

This LGTM, but since this more of the opposite of how the rest of the SDK implements async operations, could we add a comment in code or in this thread briefly explaining this change?
