Looks like it is possible to define intrusive_ptr_add_ref as

void intrusive_ptr_add_ref(T * & p)

not as

void intrusive_ptr_add_ref(T * p)

Then, it is possilbe either to increase reference count as usually or to 
clone the object if it is in non-shareable state. Would this work ? Is it 
know use case, maintained by Smart Pointers library ?
