/**
 * Defines a "single" thread model for servlet execution.
 * This empty interface allows servlet implementers to specify how
 * the system should handle concurrent calls to the same servlet.
 * <p>If the target servlet is flagged with this interface, the servlet 
 * programmer is <strong>guaranteed</strong> that no two threads will execute
 * concurrently the <tt>service</tt> method of that servlet. This guarantee 
 * is ensured by maintaining a pool of servlet instances for each such servlet, 
 * and dispatching each <tt>service</tt> call to a <em>free</em> servlet.
 * <p>In essence, if the servlet implements this interface, the servlet will
 * be thread safe.
