Low resolution of cpu times returned by getrusage

My problem is that cpu times returned by getrusage seem to be rounded to 10 
ms units (so also does time.clock).

I never noticed such a low resolution in previous versions. Since I have not 
found similar reports on the web, it probably  is not a general bug in 
(rather outdated) version 2.2.1.  Any idea what could be wrong with this 
peculiar installation? 
 
Thanks a lot!
