It may be related to the fixed bugs on 20080922.
20080929
- bugfix: NFSD issues another operation during filesystem's readdir(),
and it may cause a deadlock in aufs. check the current context is in
readdir().
:::
- bugfix: under heavy load the dead inode might be re-used because of
the race condition between S_DEAD flag and some lock-free oprations.
