    Depending on how you look at it, ps is not reporting the real
    memory usage of processes. What it is really doing is showing
    how much real memory each process would take up if it were the
    only process running. Of course, a typical Linux machine has
    several dozen processes running at any given time, which means
    that the VSZ and RSS numbers reported by ps are almost
    definitely "wrong". In order to understand why, it is necessary
    to learn how Linux handles shared libraries in programs.
