Nicely done!
Just one question: does gethrtime always give you at least millisecond
precision? I know it gives that much resolution, but I was under the
impression that actual precision depends on the platform. (In other
words, in some places, it make report values scaled out to nanoseconds,
but actually count upward in 10ms chunks.)
Actually resolution varies, but we use some sort of high res timer
on all supported platforms. Worst case resolution is prob. some
older boxen w/ 100 Mhz or so stick timers...
