I am trying to render a protein (definition file exported from vmd).
Admittedly this thing is huge (800Mb input file with 3.3 million
triangles). I am trying to do this on a 4x200 PPRO debian/linux machine
with 1.5Gb physical memory and about 4GB of swap space.

Povray 3.5 successfully reads the whole input file in about an hour and then
gives up with:

  Creating bounding slabs.
  Scene contains 3285051 frame level objects; 0 infinite.
  Slab Building Error: Out of memory.  Cannot allocate 26280408 bytes for
  bounding boxes.

Interestingly, at the time it povray complains, top reports that it is only
using about 2.6Gb of memory, i.e. there should still be about 3Gb left ...
any hints what I am doing wrong or what I could tweak to get there?
