Shuts down the executor by dropping all tasks from the queue. This method
will allow the executor to finish operations on running tasks for a
period of two seconds. After that, tasks are forcefully stopped.
<p>
The order in which the various shutdown routines of the executor are
called, is:
<ol>
<li>{@link ExecutorService#shutdown()}</li>
<li>{@link ExecutorService#awaitTermination(long, TimeUnit)} (two
seconds)</li>
<li>{@link ExecutorService#shutdownNow()}</li>
</ol>
