Since Mark seems to be listening on the list, but there's no reply yet:
let's make the requirements a bit lighter and ask some more specific
questions. I'll cut this email in two, since it is two different
questions actually.

"Expunging" a box will, AFAIK traverse all messages, look for those that
are marked for deletion and remove them. A side effect of this seems to
be, that all those traversed messages seem to get marked as "Seen" aka
"Status: O" ("old"). Is this a requirement of some sort? Isn't there a way
around it?
So if there isn't - can we fullfull our requirements, that is to leave all
flags alone, even the "Seen" one, if we don't expunge? Or can't that be
guaranteed even then?
