Well, after 50 minutes and 15 lines, I confirm that the -MB solved the
problem! I didn't have the patience to wait for another 20 hours
though ;-)

Reading up on MB and friends, I thought that the Bounding box problem
wasn't likely to be the culprit, but I thought it was more likely a
problem with the light_buffer (which is switched off with the -MB switch
automatically).

And behold, +MB25 (the default) and -UL did solve the problem too, but the
rendering was still immensely faster (2 minutes for the entire image)!

Thanks for pointing me in the right direction, Mike!
