    Increase BUFFSIZE to handle very large /proc/stat files
    
    We read /proc/stat using a statically sized buffer. This was increased
    to 64kB in 2005 via commit 777fcd3cf15d "/proc/stat for 1024 CPUs".
    
    Unfortunately in 2020, 1024 CPUs is not enough for anyone. I have a
    large machine where /proc/stat is 74kB, and vmstat gives incorrect
    output.
    
    Double the buffer to 128kB in the confidence that 2048 CPUs is actually
    enough for anyone.
