The guys have been discussing this on the forum, for example:

Yes, aufs lacks diligence, leaves behind whiteout files that are no longer needed.
The script that saves the session, including for containers, is /etc/rc.d/rw-merge
I have added code to it to purge invalid whiteout files. That will slow down shutdown, it remains to be seen if by a noticeable amount of time.
I considered doing the whiteout purge less frequently, in the
initrd when there is a version update, but we shall see how this
goes, doing it every shutdown.
