I barely know Python, so there is nothing I can do about this. But if you
have a better solution, it would be worth trying it. I feel a bit uneasy
about Sage, when we can't trust the mechanism for testing it.
It's odd why failures on some test is pretty repeatable when running
{{{make ptestlong}}} but run individually, they pass. I'm pretty sure that
is not a memory issue, as I've noticed that on my Sun Blade 2000 SPARC
where I'm the only user. That machine has 8 GB RAM and only two processors
(its not multi-cored or multi-threaded), so I don't run more than 3 tests
in parallel.
