... It may be possible there are other order-dependent behaviors,

There are, but ...

so it would be really good if people who have time can run the tests with -r on whatever platforms are available and report any other anomolies.

By far the most frequent cause of errors when using -r is bogus module objects left behind in sys.modules on non-Unix platforms that can't import some Unix-specific things. A later attempt to import the same module again doesn't fail, but since the module object is incomplete it fails for some other reason when a test attempts to use the module.

I spent countless hours worming around this in the past, but lost heart for it; on my Win9X box, the failing test has usually scrolled off the (50-line) DOS box before regrtest completes, and so also the history of the test ordering that caused it. Heh -- -r failed in test___all__ while I was typing this, but I've no idea why. I'll pursue it until I get sick to death of it .
