Well, the compiler can in theory ellide atomics if it csn prove 
that the memory cannot be accessed by another thread.

But it kinda is missing the point that if it only is in a single 
thread then it would typically only have only one assignment. 
Shared_ptr is for holding a resource not for using it...
