After reading this I did two more traces:

RadCont.jpg : Perforated cylinder, plane, mediacontainer without media,
radiosity on.

RMnoCont.jpg : Perforatad cylinder, plane, black box in backgroung, media
without container and radiosity on.

So here I am, with what I wanted to avoid in the first place, slow and
grainy media without a container object.
Well, learned something going trough this.
