Hmm, are those wood planks isosurfaces?

Glass with radiosity can be quite slow, but 1d17h is not very extreme for
such a scene.  I had a similar situation in my picture for the 10best
cover image contest and it came near a halt (~30min per line) on my old K6
when reaching the glass objects.  There were photons and a lot of
isosurfaces too of course.

Something that would really help in such a situation would be a
no_radiosity modifier for objects.  You could create a second bowl for
radiosity with no_image, no_shadow and no_reflection and a simple material
and use no_radiosity for the real bowl.

The fruits look great, apart from the leftmost apple floating in the air
of course.  Is there subsurface scattering on the orange?
