Aughr, this could explain some weirdness that I'm seeing on IDE kiobuf
atm. Basically, kio and "plain" xfs works just fine and I can't crash
it. No corruption either. But kiocluster corrupts data here too...

And currently I don't see why. For IDE, the kio clustering just means
that the same request will be started more than one time. I'll try and look
closer at this tomorrow.
