I don't believe that. The system caches all sorts of stuff in RAM all
the time (which is obviously much more responsive than swap). And I
still have a swapfile, it's just empty all the time.

That warning's undoubtedly from someone who doesn't get the
difference between swap and virtual memory (probably stuck in Classic
Mac OS concepts/misunderstandings like I was 'til recently).

I've noticed no problems copying/moving files since killing swap.
Indeed, I found an iDVD project built fine without swapping.

So multiply that by several times and you can imagine what I'm
experiencing with no swapping.

Is that report(s) in addition to the link I posted for compiling a
new dynamic_pager? (That post didn't use any dramatic words.)

Please, and thank you,
