* @brief Used to keep track of a thread's activities within its entry
* point function.
*
* A ACE_Thread_Manager uses this class to ensure that threads
* it spawns automatically register and unregister themselves
* with it.
* This class can be stored in thread-specific storage using the
* ACE_TSS wrapper. When a thread exits the
* <ACE_TSS::cleanup> function deletes this object, thereby
* ensuring that it gets removed from its associated
* ACE_Thread_Manager.
