Many thanks; that succinctly explains the situation and makes sense. Yes, I've
noticed that, if I wait and be patient for awhile without re-booting, and load
other programs, the disc-swapping begins to subside.

That has been a mystery to me for quite some time; when I first noticed it years
ago, I thought my computer had suddenly been infected by a virus or similar. I
never made the connection between POV-ray's disc-swapping and the subsequent
(temporary) overall slow-down.
