--- Comment #9 from Juan Lang juan_lang@yahoo.com 2008-03-25 11:19:55 --- I've written some tests about this. Turns out that second update doesn't have anything to do with streaming mode. Rather, it has to do with detached messages. I suspect the update after the "final" update sets the detached portion of the content, i.e. the signature.
