* that no two threads will execute concurrently in the
* servlet's <code>service</code> method. The servlet container
* can make this guarantee by synchronizing access to a single
* instance of the servlet, or by maintaining a pool of servlet
* instances and dispatching each new request to a free servlet.
*
* <p>This interface does not prevent
* synchronization problems that result from servlets accessing shared
* resources such as static class variables or classes outside
* the scope of the servlet.
