Should getmicrotime() really be prefered in all cases ? From
kern_clock.c, it looks like microtime() has much less overhead when
you don't need a very accurate timestamp:
For each there is fast but less precise
version "get{nano|micro}time" which will return a time which is up
to 1/HZ previous to the call, whereas the raw version "{nano|micro}time"
will return a timestamp which is as precise as possible.
