and here's the blazing fast 3.7 render!  Mighty impressive this new
multiprocessing radiosity code!  Thanks clipka!  The other took quite a few
minutes, this one

Render Time:
  Photon Time:      No photons
  Radiosity Time:   0 hours  0 minutes  4 seconds (4.537 seconds)
              using 20 thread(s) with 26.971 CPU-seconds total
  Trace Time:       0 hours  0 minutes 26 seconds (26.965 seconds)
              using 4 thread(s) with 99.071 CPU-seconds total
POV-Ray finished


on a Q6600... radiosity was done before I could see anything! o_O
