It's easier to write if you wrap boost::detail::shared_count. That way you'd 
even be able to form weak pointers (although I'm not sure we have the 
necessary public interface for that.)

shared_ptr<void> works as a deleter too, this keeps us entirely within the 
public interface, but we'll waste a pointer. Although with it you'll be able 
to use make_shared inside make_poly_unique.
