Yeah but still, 30%?? Kinda huge drop IMO. Makes a nonsense of inter-version comparisons, which is why I'm sticking to 2.44 for
benchmarking. And remember this is just for a very simple scene; quite possible the speed loss would be much worse for a complex scene.

I noticed. Personally I don't like the way the threaded stuff works at all. Sometimes it doesn't start using more than one thread
until after the first block has been completed, there's a major stutter when each thread completes which can be nasty if a whole bunch
finish at more or less the same time, and once the no. of remaining blocks is less than the no. of threads then the parallelism drops
off completely (very poor if the last coupla blocks happen to be complex). Ah well, better than nothing.

I know it's just a very simple test program by comparison, but I like the way C-ray does it. Parallelism is always maxed as much as it
can be since it's done by scanline.
