I guess that I wrote the code without noticing unique()s existence. 
However, I now know of it (thanks ;-) and have checked the code in 
boost/detail/shared_count.hpp:

    bool unique() const // nothrow
    {
        return use_count() == 1;
    }

I find that this is exactly what I use myself, so will modify my code 
to use shared_ptr<>::unique().
