Which begs the question, could a future improvement of POV be to make it
more "memory-intensive"?

If the question is a dumb one, please forgive me.  I'm an expert (IMHO)
in the materials science behind manufacture of ceramic packaging for
chips, but am quite ignorant of how computers actually work. But could
it be that POV is "using up float-processor space" for things that could
be shoved over to the "memory"?   

Also, I think I would have noticed a whole lot of hard disk drive
activity if the old Bryce were swapping out, wouldn't I have?
