> In looking at flattening the metrics there are a couple of issues with the ThreadReuseExecutor:
> 1. The getStats method uses unsynchronized access to get the queue size.
> 2. The queue ordering prefers older work items to newer - even after repeated queuing.
> 3. Thread tracking could be more concurrent.
