Does reiser4 even try to solve any of the nasty problems Val mentions (the fsck crunch, the need for internal integrity checks, et al)?

As far as I can tell it doesn't. It used to have nice support for small files, but that got turned off because it impacted benchmarks and I don't know if it was ever turned on again.

One thing mentioned in the article which reiser4 does implement (though
Val doesn't include it in her list of examples) is copy-on-write atomic
storage hierarchy updates -- depending on settings, changing an inode can
result in allocation of new copies of the block containing the inode and,
recursively, every parent block which references the change, right up to
the master block. The old versions are only freed once the root has been
'committed' to its canonical location.
