Actually, sorry, that's not *exactly* what I'm doing -- I'm creating a 
new TSortedCollection, using ForEach to iterate through the old 
collection to Insert into the new one, and then destroying the old one. 
  This copies only pointers (and runs through the Compare method) and is 
actually pretty fast -- it's just not elegant.

If I stored the entire thing to a memory stream, it would copy all of 
the data and every re-sort would go pretty slowly.
