title: HttpServlet does not implement runnable or extend thread, why is it thread-able?
body: <p>For an object to be runnable, it needs to implement the <code>Runnable</code> interface or extend the <code>Thread</code> class, however, it does not seem that <code>HttpServlet</code> does any of these.</p>
  
  <p>How come <code>HttpServlet</code> can be threaded or have i mistaken? </p>
