At the moment, if a logical file has expired and is a member of a superfile, Sasha will not delete it (Sasha logs that it can't because it's part of a super file).
Additionally, when there are a lot of expired files like this, it takes a long time to process them all, probably because it is looking them up and locking them before finding out they are owned.
1) Expired sub files be automatically removed from their superfile and deleted anyway?
2) Superfiles have their own EXPIRY setting, or should there be an option to auto-delete when the last sub-file is removed (NB: could be self-contained feature)
3) Keep current semantics (supers protect expired files), but fix the speed issue.
