I was aware of that, but it seemed to be worth reporting this failure. > I am taking a look at this shortly. I don't have hardware on which I can push > parallel make so far.

There's nothing stopping you running 10-20 threads on a single processor machine. The scheduling algorithm in the operating system would still switch the active processes around, and one compilation would start before another ends. So I believe even a single core machine, with Sage built in parallel, could exhibit this problem. If it was helpful, I could set this up later and build pari 100 times and log where it fails. But I'm not at home, and not able to do that now. (Yes, I could ssh in and set it up, but it needs more thinking about than time I can devote to it now, while using a laptop on batteries).
