Hello everybody,

reading run(), I noticed gettimeofday() is being used to measure
This is not good practice[0], given gettimeofday is inaccurate for this
matter (take time-jumps for instance). POSIX.1-2008 even marks it as
This patch will move the entire timing-system over to clock_gettime
()-calls with a monotonic clock to enable a consistent timing
This didn't require dramatic changes to the code and reduced the binary
size for me by almost 200K!
