Support for <atomic> in earlier C++11 implementations wasn't reliable enough
compared to shared_ptr's platform-specific implementations.
Things nowadays have probably already reversed though, with <atomic> being
more reliable. I could turn it on by default when BOOST_NO_CXX11_HDR_ATOMIC
isn't defined, which according to Boost.Config would enable it on g++ 4.9
