There are only 4 leaf and 4 bark textures for the plants plus a complex
ground/rock texture. Additionally there are 2 height_fields on which I put
the plants using pigment_eval(). All in all much less than in most of the
scenes I did before without any problems.
Maybe the problems comes from the plants, the meshes have approx. 12 MB. On
the other hand peak memory for the render was only about 350 MB.

I thought Win XP can handle 4 GB but I'm not sure and more specific I don't
know if there is a difference between the professional and the home edition
in this respect.
