It is strange. The attached image is a simple scene with a mesh2 object 
(twice). A first render with only one light source took 8m39s; a second, 
with an added shadowless light, took 8m52s; a third render (attached) 
with the second light /not/ shadowless, took 10m20s.

We are far from a quadruple render time... I have no idea.

I wonder whether the normal vectors in the rightmost object somehow ..
interfere.  no idea, have attached the code I use.  nearly forgot - the
output_file_names in the ini file will need adjusting.
