What is it about subclassing Thread that is enormously useful? I can't
immediately think of any case where a scoped local couldn't achieve the
same thing. Instead of

   (MyFoo)Thread.current();

you'd have

   CurrentFoo.get();

... which would work in lightweight and heavyweight Threads. Is there
something that definitely wouldn't work with this mechanism?
