Here's another one, with slightly less blurring because I rendered it on 
my P200 rather than my Athlon.  It's notable for the jaggy lines in the
checkerboard floor...

Rendered with a development build of 3.5, but with a custom patch.  Whether
that patch makes it into 3.5 or into the next MegaPOV is something I need to
discuss with some people.  Render time was 4:32, which isn't bad for a P200.
The cylinder was supersampled 25 times per ray (vs. 1089 for the images I 
posted before.)

So what's so special about this patch compared to the old reflection blur?
Well, let's just say it's not limited to reflection, shall we?
