Yes, you got the point.

I see that you should use getrusage to time if you can. Because
you get generally immunity to other load.

There is problems with getrusage. At linux v2.2/glibc v2.1 real
resolution is only 0.01s. Therefore it is not suitable to time
all tasks. My approach needs also gettimeofday to get additional
accuracy, with less reliability.
