It seems that I'll have to re-add the unification of proxies because 
what happens if you have bad code like:

void foo(root_ptr<int>);

root_ptr<int> p = new<int>(9);

foo(p);

cout << * p << endl;

It won't work if I simple transfer ownership when copying root_ptrs. 
The good news is if I unify proxies then all the problems will be solved.
