Re: managing helma collections

I didn't get a chance to read Tobi's actual bug report before writing my
email and so I realise now I misunderstood the point of his email being
about performance/scalibility with sorting large collections (ie. large
mailbox) rather then about the functionality of getOrderedView().

And from a scalability point of view, I think it does make sense to
order a collection (mapped to an sql db) using sql rather then in-memory
sorting since otherwise for very large collections you won't be able to
sort collection that don't fit into the memory cache (or have I
misunderstood that?).
