I'm not sure: I don't know whether and to what extent focal blur impacts
memory usage - the scene uses a fair bit even without blur. Still, it seems
definitely related to switching the feature on: when I comment out the
'aperture' or the 'blur_samples' line in the camera definition (thereby
switching off focal blur), the scene renders fine again.

However, it now seems there might be a problem: the minimal scene below cut
from the original glass scene uses hardly any memory at all and gives the
same problem whenever focal blur is on. It runs fine in povray 3.6 though.

Hope this helps, Jeroen.
