InternalDriver creates a thread pool for running timed logins like this:
private static final ThreadPoolExecutor _executorPool =
new ThreadPoolExecutor(0, Integer.MAX_VALUE, 60L, TimeUnit.SECONDS,
new SynchronousQueue<Runnable>());

The java.util.concurrent.Executors class has factory methods that create thread pools and hide the details such as choosing keep-alive time and which kind of queue to use.
