Well, since it's a race condition it's obviously going to be sensitive to
machine speed. I think that Perl version, or more likely version of
IPC::Run or a related module, may enter into it too. prairiedog has
gotten through the tests several times since yesterday without failing,
yet it's significantly slower than the other PPC Mac I was able to
consistently reproduce the problem on. I don't think those two have
the same vintage of Perl installation, though, so Perl version seems
like a likely explanation.
