I think we should get a version of the patch in that removes all files
in a directory on cleanup, but warn if a subdirectory is still there.
James has a patch to fix the one issue we've seen so far with existing
child directories.

After that, we should work on fixing the users that leave files
behind, and can possibly stop cleaning up files, if we want to.

That is unrelated to Eric's patches, They just added the dump, which I
tried to trigger. It's not entirely clear what caused the filesytem
damage, but I was definitely able to reproduce the unclean shutdown
without any of Eric's sysfs patches.

Thanks,
Kay
