No, it is definitely not overestimated. It is more likely to rather be the opposite and you will find this out if you try to use dtrace or attend a demo. Dou you know of any other system where you can say: Print me a strack trace with symbols for all processes on this computer (even stripped ones) that call gettimeofday() within the next few seconds. Note that you do not need a special kernel, no reboot, no restart of applications. There are a lot more possibilities including tracing kernel routines on a production kernel but it would take too long to describe them....
