| * Ensures that servlets handle |

| * |
| * <p>If a servlet implements this interface, you are <i>guaranteed</i> |
| * 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. |
