I've been experimenting with:

template<class T, class D = detail::apply_delete>
class move_ptr;

So far I like it.  It is implemented so that the deallocator can also 
be a reference to a deallocator.  Can be used like:

template<class T>
template<class Y, class D>
shared_ptr<T>::shared_ptr(Y* p, D d)
        : ptr_(p)
{
        move_ptr<Y, D&> hold(p, d);
        s_ = new detail::shared_ptr_deleter<Y, D>(p, d);
        hold.release();
        ...
}
