One more thing to try, I suppose, is -DBOOST_SP_USE_STD_ATOMIC with libc++ 
instead of libstdc++. Thread sanitizer is supposed to understand the __c11 
built-ins and I expect libc++'s std::atomic to use them.

I was going to implement a version of sp_counted_base using the __c11 
built-ins and make it default on Clang, but never got around to it.
