Hi Brian,

By using volatile read and CAS, there's still a chance that multiple 
concurrent threads will be invoking the layoutChars(true) concurrently, 
but you guarantee that only a single instance of String will ever be 
returned as a result of the toString() method. Is that what you were 
pursuing?
