Actually, using Boost.Bind will use a lot more memory overall.  Would
it not be better to create a static function somewhere, something
like:

class SceneManager
{
    ...
    static deallocSM(SceneManage *ptr)
    {
        ptr->clearScene();
    }
    ...
};

And create as:
SceneManager *s=fromSomewhere();

boost::shared_ptr<SceneManager> p(s, &SceneManager::deallocSM);

Doing this means it only keeps a pointer to the function call, instead
of through a bind instantiation, meaning this will execute ever so
tiny slightly faster, as well as take less space?  It has been a while
since I created a new handler like that, but I 'think' the function
takes a pointer to the embedded pointer type, check the smart_ptr docs
for details I guess.
