- * @class ACE_Reactor_Token_T
- *
- * @internal For ACE internal use only.
- *
- * @brief Used as a synchronization mechanism to coordinate concurrent
- * access to an ACE_Reactor_Impl object.
- *
- * This class is used to make access to a reactor's internals and
- * demultiplexing mechanism thread-safe. By default, the thread that
- * runs the handle_events() loop holds the token, even when it is blocked
- * in the demultiplexer. Whenever another thread wants to access the
- * reactor, such as via the register_handler(), remove_handler(), etc.
- * methods, it must ask the token owner for temporary release of the token.
- * To accomplish this, this class reimplements the ACE_Token::sleep_hook()
- * method through which the owning thread can be notified to temporarily
- * release the token if the current situation permits.
- *
- * The owner of the token is responsible for deciding which
- * request for the token can be granted. By using the
- * ACE_Token::renew() method, the thread that releases the token
- * temporarily can specify to get the token back right after the
- * other thread has completed using the token. Thus, there is a
- * dedicated thread that owns the token by default. This
- * thread grants other threads access to the token by ensuring
- * that whenever somebody else has finished using the token the
- * original owner reclaims the token again, i.e., the owner has the
- * chance to schedule other threads. The thread that most likely needs
- * the token most of the time is the thread running the dispatch loop.
