The regression tests have never pretended to test more than a fraction
of what might be interesting to test. Crash recovery, in particular,
has always been interesting and has never been tested in any mechanized
way. They don't really exercise concurrent behavior in any meaningful
way either. I don't think they're "showing their age" so much as we're
starting to get more ambitious about what we would like to have routine
testing for.
