According to what I read on a different thread this happens quite regularly at CDG, and I suspect word must have got round to Immigration Officers elsewhere.
Also, land borders between Switzerland and France are often unmanned, so people who entered via that route will often not have a stamp (but this will not be an issue for much longer seeing Switzerland is in the process of joining the club and will then be issuing its own Schengen entry stamps)
