Well, your oldish laptop likely is more modern than the machine I use
for testing. I'll increase CPU time for the four tests again.

3MB isn't a lot, so swapping should not be an issue. However, I doubt
the test is I/O bound for any reasons other than possible swapping. I'm
clueless here. I'll increase the wall clock time limit, too.
