Review Comment:
   yeah, I think it's a cool one-liner, assuming that repeatedly calling 
ThreadPools::getWorkerPool is not expensive, which is true because it just 
returns the pool from the 2nd call:
   ```
     public static ExecutorService getWorkerPool() {
       return WORKER_POOL;
     }
   ```
