+/**
+ * Defines the possible values for the POA thread policy.
+ *
+ * This enumeration can obtain the following values:
+ * <ul>
+ * <li>ORB_CTRL_MODEL Each object in POA has a separate serving thread
+ * and a separate server socket, listening on the objects individual
+ * port. Additionally, when the request is accepted, it is also
+ * served in a separate thread, so several requests to the same
+ * object can be processed in parallel. The servant can always get
+ * the Id and POA of the object it is currently serving by
+ * invoking {@link Servant#_object_id()} and {@link Servant#_poa}.
+ * These two methods use thread to data map and must work correctly
+ * even then the servant code is executed in several parallel threads.
+ * </li>
+ * <li>SINGLE_THREAD_MODEL All objects in POA share the same server
+ * socket and are served in the same thread. This model is applicable
+ * when the number of objects is greater than the number of threads
+ * and (or) ports, supported by the system.</li>
+ * </ul>
+ * OMG also defines a MAIN_THREAD_MODEL, currently not supported by
+ * the java API.
