Maybe the ESTALE came from somewhere else.. What filesystem is used to
store the venus cache. I just did a quick grep in a 2.6.4 tree and found
that a couple of filesystems like to return their own ESTALE errors,

    afs, exportfs, fat, jfs, lockd, nfsd, nfs, reiserfs

(likely candidates here would probably be reiserfs or jfs)

That's ok, this just adds another datapoint to keep my eyes open for
possibly similar reports.
