OK, thanks.  A few comments...

Your class is missing:
        scoped_timed_lock
        void do_lock(cv_state &);
        void do_unlock(cv_state &);

which is probably not a big deal if it only used for shmem, and only
used with shmem::shared_condition.

However, you would not be able to use this class as a drop-in
replacement for any of the other thread::*mutex classes, because it
would require reasonable interoperability with boost::condition.
