Howard Hinnant 9b35c8275c Dave Zarzycki showed how the efficiency of shared_ptr could be significantly 
increased.  The following program is running 49% faster:

#include <iostream>
#include <memory>
#include <chrono>
#include <vector>
#include "chrono_io"

int main()
{
    typedef std::chrono::high_resolution_clock Clock;
    Clock::time_point t0 = Clock::now();
    {
        std::shared_ptr<int> p(new int (1));
        std::vector<std::shared_ptr<int> > v(1000000, p);
        v.insert(v.begin(), p);
        v.insert(v.begin(), p);
        v.insert(v.begin(), p);
        v.insert(v.begin(), p);
    }
    Clock::time_point t1 = Clock::now();
    std::cout << (t1-t0) << '\n';
}

Howard Hinnant 2b672e24a5 Still working on the basic design of <atomic>. I'm working towards a system by which the compiler only needs to define the strongest intrinsics it can. Weaker atomics in the library automatically try stronger and stronger variants, picking the weakest compiler intrinsic available. If no compiler intrinsics are available for a given operation, the library locks a mutex and does the job. Better documentation to follow...
