/**

* $Id$
*
* 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."
