- *  @file    TP_Reactor.h
- *
- *  $Id$
- *
- *  The ACE_TP_Reactor (aka, Thread Pool Reactor) uses the
- *  Leader/Followers pattern to demultiplex events among a pool of
- *  threads.  When using a thread pool reactor, an application
- *  pre-spawns a fixed number of threads.  When these threads
- *  invoke the ACE_TP_Reactor's handle_events() method, one thread
- *  will become the leader and wait for an event.  The other
- *  follower threads will queue up waiting for their turn to become
- *  the leader.  When an event occurs, the leader will pick a
- *  follower to become the leader and go on to handle the event.
- *  The consequence of using ACE_TP_Reactor is the amortization of
- *  the costs used to create threads.  The context switching cost
- *  will also reduce.  Moreover, the total resources used by
- *  threads are bounded because there are a fixed number of threads.

-/**
- * @class ACE_TP_Reactor
- *
- * @brief Specialization of ACE_Select_Reactor to support thread-pool
- * based event dispatching.
- *
- * One of the shortcomings of the ACE_Select_Reactor is that it
- * does not support a thread pool-based event dispatching model,
- * similar to the one in ACE_WFMO_Reactor.  In ACE_Select_Reactor, only
- * thread can call handle_events() at any given time. ACE_TP_Reactor
- * removes this short-coming.
- *
- * ACE_TP_Reactor is a specialization of ACE_Select_Reactor to support
- * thread pool-based event dispatching. This reactor takes advantage
- * of the fact that events reported by @c select() are persistent if not
- * acted upon immediately.  It works by remembering the event handler
- * which was just activated, suspending it for further I/O activities,
- * releasing the internal lock (so that another thread can start waiting
- * in the event loop) and then dispatching the event's handler outside the
- * scope of the reactor lock. After the event handler has been dispatched
- * the event handler is resumed for further I/O activity.
- *
- * This reactor implementation is best suited for situations when the
- * callbacks to event handlers can take arbitrarily long and/or a number
- * of threads are available to run the event loop. Note that I/O-processing
- * callback code in event handlers (e.g. handle_input()) does not have to
- * be modified or made thread-safe for this reactor.  This is because
- * before an I/O event is dispatched to an event handler, the handler is
- * suspended; it is resumed by the reactor after the upcall completes.
- * Therefore, multiple I/O events will not be made to one event handler
- * multiple threads simultaneously. This suspend/resume protection does not
- * apply to either timers scheduled with the reactor or to notifications
- * requested via the reactor. When using timers and/or notifications you
- * must provide proper protection for your class in the context of multiple
- * threads.
