Hmm, I can't see any reason for these tests to fail in a non-deterministic way. This sounds like it could be a serious bug. And if happens on machines other than the Hydra ones, the bug is almost certainly in Emacs. I think we need to add some logging statements to figure out what is going. I will try to figure how to do that.
