Main/glue: Updated NativeEventQueue::processEventQueue with more details on darwin and Ctrl-C. bugref:9898

File:

trunk/src/VBox/Main/glue/NativeEventQueue.cpp

+              r95182
  *          out of bounds.  On darwin it will also be returned if the queue is
  *          stopped.
+ *
+ * @note    On darwin this function will not return when the thread receives a signal,
+ *          it will just resume the wait.
