* 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.
