Notes:
- A Worker is a thread that performs a Runnable.
- When the worker thread completes the execution of the runnable, the worker thread
and its memory are automatically reclaimed.
- The runnable itself is not deleted by the worker; it will thus outlive the worker
that runs it.
- Exceptions thrown by the runnable cause early termination of the runnable.
