Yeah, 90% doesn't feel right to me. In C++ I try to use 
unique_ptr instead of shared_ptr wherever possible but I find I'm 
often not able to because my references need to be held in 
several places for efficiency. I'd say I'm more like 90% 
reference counted, 10% unique throughout my 300kloc codebase.
