IMHO it sounds like the Mac you're using has enough similarities to
Windoze to suffer some similar problems. I'd imagine that there's some
grabage management/memory management that's suffering slowdown because
POV isn't releasing enough CPU power to the OS. If I'm roughly right
then the only way to improve consistency would be to lower your
render's priority - which may or may not end up in a slower overall
render time.

Myself I render in batches partly because a lot of my frames take
hours to render. I have .ini file settings which allow one PC to work
on a hundred frames or so while another PC works on a different
subset.
