/**
 * Ensures that servlets handle
 * only one request at a time. This interface has no methods.
 *
 * <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 engine
 * 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>If a servlet implements this interface, the servlet will
 * be thread safe. However, 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.
