	Does nothing.
void	_Thread_queue_Deadlock_status (Thread_Control *the_thread)
	Sets the thread wait return code to STATUS_DEADLOCK.
void	_Thread_queue_Deadlock_fatal (Thread_Control *the_thread)
	Results in an INTERNAL_ERROR_THREAD_QUEUE_DEADLOCK fatal error.
void	_Thread_queue_Enqueue (Thread_queue_Queue *queue, const Thread_queue_Operations *operations, Thread_Control *the_thread, Thread_queue_Context *queue_context)
