+/**
+ * The "DelayedReturn" class implements delayed returning from functions.
+ * 
+ * For instance, suppose you would like to return from a wait() operation
+ * only after a certain time has passed, without blocking other clients
+ * from using your interface during this time.
+ *
+ * Your implementation (in the skel file) of wait should look like this
+ *
+ * <pre>
+ * static DelayedReturn *delayedReturn = 0;
+ *
+ * bool TimeServer::waitUntil(long time)
+ * {
+ *     if(time(0) < time)
+ *     {
+ *     	   // ... initialize timer here ...
+ *         delayedReturn = Dispatcher::the()->delayReturn();
+ *     }
+ *     return false; 
+ * }
+ *
+ * void timerEvent()
+ * {
+ * 	   delayedReturn->doReturn(true);
+ * }
+ * </pre>
+ *
+ * NOTE: this class breaks for local use (i.e. you can only use it if the
+ * call was a remote call), so it is strongly recommended not to use it
+ * unless there is no alternative (and you should really know what you are
+ * doing, too).
