+/**
+ * @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.
