Actually please don't try it!

I just tested dbench with xattrs and got 5 more different lock
inversions (brought with soft lockups ;). I just fixed all of
them with 5 more patches, I just don't have pushed them yet,
waiting for a night in my bed before writing the changelogs.

Will push/post them tomorrow.

Thanks!
