Well, I have frequently run this machine pretty much up to the
limits of what it can run, in order to force paging/swap, and
not noticed any problems except that it gets very slow. Also,
if the DMA code itself were the problem, that's where it would
segfault, not in the prime program. Right?
I'd need to download the latest version and try again with
DMA off. Hmm. It occurs to me that I have an external USB
drive. It should be easy to install and run from there,
and then DMA would not be an issue.....

I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
