In simple terms: While you're changing the aperture (f/ number) the camera is compensating for the extra light by shortening the exposure time.

Call me crazy, but isn't that what you expect, if you change the aperture? Otherwise the only result would be over- or under exposure of the photo. I don't think shutter speed has anything to do with DoF. Or am I wrong?
