There seems to be a huge memory leak which becomes noticeable if you use focal
blur on a scene with high-frequency noise. I suspect it's not cleaning up all
the additional rays it fires per pixel, and noisy scenes need a huge number of
rays.
Here's a simple example scene:
camera {
location -z*4
aperture 0.2
focal_point 0
blur_samples 64
confidence 1 variance 0
}
light_source { <-1,1,-1>*100, rgb 1 }
sphere { 0, 1 pigment { crackle solid scale .001 colour_map { [0 rgb x][1 rgb
x+y] } } }
cylinder { -y, -y*2, 3 pigment { rgb z } }
background { rgb .7 }
Watch pov's memory usage when it starts tracing against the sphere.

Doh!
But I like crackle!
