Yes, I expected this before starting the whole thread.  And I guess my
fresnel windows are making the situation worse, as many of the samples will
hit the glass in such an angle that they get reflected back in to the room
even when I'm not looking at the windows.  Which of course is as it should
be, but I *have* been thinking of a pass_through for radiosity :)

Thanks!

My sun is just a point source, no looks_like, instead I've got a cylindrical
pigment intersecting the sky sphere in sun's direction.  I really can't
justify this design, probably it was just a way of doing something unusual
on the day I created it.  And it doesn't look *hopelessly* ugly! :)
