	They simply create/destroy kernel mutex objects. Which can then be  
locked/unlocked kernel L4_mutex() system call. This is all wrapped by  
the Mutex Library, if you want to use kernel mutex objects specify  
mutex_type=kernel on the build line which configures the Mutex library  
to do this.
	Have a look in libs/mutex for details.
