I don't get this point. The monitor field can just be the single 
pointer that is not transitively immutable? I mean. The compiler 
knows *exactly* when you access the monitor field. It's never 
accessed manually! This is a pointer access that can be generated 
at exactly line of code in the compiler. Just drop immutable 
there.
