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.
