+/**
+ * @file Reactor_Notification_Queue_Test.cpp
+ *
+ * $Id$
+ *
+ * Verify that the notification queue can be used with large numbers
+ * of events.
+ *
+ * Normally the ACE_Reactor uses a pipe to implement the notify()
+ * methods.  ACE can be compiled with
+ * ACE_HAS_REACTOR_NOTIFICATION_QUEUE, with this configuration flag
+ * the Reactor uses a user-space queue to contain the notifications.
+ * A single message is sent through the pipe to indicate "pipe not
+ * empty."
+ *
