>Libatomic_ops should eventually be configurable to just use C11/C++11 atomic operations. That hasn't happened yet, but should be fairly easy. Or, if we wait long enough, we could just use the C11 primitves directly. Historically libatomic-ops preceded and influenced the C11/C++11 interface, but the C11/C++11 interface is a much better design (another iteration, a lot more careful thought by many more people, etc.)
