the only thing that can be done for this is to populate the message-list
as the summary information comes in from the server (but this very
difficult to do since ETable's performance wrt this is horrible). we
can't make the scan any faster because of all the features users want
(like attachment icons, mailing-list vfoldering, etc) which requires a
huge amount of information from the server.

once all the summary information has been "seen" by evolution, it goes a
lot faster, but still takes a while because we have to ask for the flags
for all messages to update our summary with any flag changes that may
have been done since our last folder visit.
