Did you test it? In my case wait returns when the predicate is false. I use
an empty circular buffer and call from the same thread this code:

        using namespace boost;

        scoped_lock lock(mutex_);
        wait_for_free_slots_.wait(lock, bind(&buffer_type::full, buffer_));
//wait_for_free_slots_ is a condition variable

        buffer_.push_back(item);
        wait_for_items_.notify_all();

This line returns immediately
wait_for_free_slots_.wait(lock, bind(&buffer_type::full, buffer_));
//wait_for_free_slots_ is a condition variable

If you inverse the predicate it blocks forever.

Thanks,
