This only matters if the only thing you do is initialize. This is best-case 
scenario for reference-linked for both performance and memory use. How often 
is that the case in real code?

Then there are thread safety, custom deleters, weak_ptr support, 
enable_shared_from_this, and competition from intrusive_ptr on the low end, 
which should be even faster in ST mode.
