This wakeups the Reactor_Impl if currently blocked. Pass over
both the Event_Handler *and* the mask to allow the caller to
dictate which Event_Handler method the Reactor_Impl will
invoke. The ACE_Time_Value indicates how long to blocking
trying to notify the Reactor_Impl. If timeout == 0, the
caller will block until action is possible, else will wait until
the relative time specified in *timeout elapses).

handle_input method
will iterate and dispatch the ACE_Event_Handlers that are
passed in via the notify queue before breaking out of the event
loop. By default, this is set to -1, which means "iterate until
the queue is empty." Setting this to a value like "1 or 2" will
increase "fairness" (and thus prevent starvation) at the expense
of slightly higher dispatching overhead.
