cscott and mstone discovered and analyzed a update-related bug from Sep. 17-19 that, when encountered, corrupts files' gid fields.
Bertl (Herbert Poetzl) also analyzed the bug and discovered that it was more widespread than we initially believed: he showed that it affects all CoW hard-links (which we intend to use extensively through-out our filesystem, for Trial-3).
He has developed a kernel patch that he believes will fix the problem.
He also developed a minimal test-case that we can use to verify the fix.
