Indeed. Unfortunately, since this is my office desktop PC, I'm quite
reluctant to fiddle around with it too much. But perhaps I find an
older live CD to try this with.

Sounds perfectly reasonable.
So I understand that there are no known issues with XFS that might
explain this long term fragmentation behaviour, and that there are no

I'll see what tests I can do and report back about the findings.
