maybe this is just a symptom.  When was the nfs4 code converted
to just use a single open struct file, and what are the lifetime
rules for it?  It would easily be that a long alive file might
make XFS keep persistent preallocations longer or similar issues.

Adam, can you create a loop filesystem with ext3 or something else
on it and see if the problem is XFS-specific?
