Didn't you forget to attach a condvar to every non-trivial object as
well? Just imagine how useful it is to have it ready for signalling and
for waiting for changes to the object!

.... and then we end up with a "class Everything" that provides all the
imaginable possibilities to the user, including automated check against
famous Uenal Mutlu deadlock theorem. We have reached ultimate
perfectness! Congratulations! The only problem is that it seems that
nobody but Uenal Mutlu will use the language then.

.... mostly due to the fact that one famous OS doesn't provide a sensible
way to deal with non-trivial IO without threads and has pure support for
processes, IMHO. Hard times during which programmers learn *not to use
threads* where they are inappropriate I foresee :(
