Comment 6 for bug 1185851

@jokke

This was put on hold following discussions in the glance meetings and I have not had a chance to come back to it. We decided that the proposed solution needing improving to be able to support doing cleanups fully asynchronously instead of current method of using delete event as trigger which could cause unexpected timeout if large amounts of cleanups are required. We would also need to extend the locking logic as it would need to be shared between deletes and cleanups (and more?).
