Two more test renders. After 18 hours 28% of the image completed, and 
then dropped to the PPM range instead of PPS when it got to the crowded 
bits.

Another test render. I seem too have eliminated a few more bottlenecks. 
This one only took 15273.62 seconds with all features turned on except 
the atmospheric media.

Forgot the image. ;)

Anyway, the atmospheric media seems to be the main remaining bottleneck. 
Not sure how to make it perform faster.
