But to be interoperable with other maildir clients, Dovecot can't know 
if someone else didn't do other changes within the same second. So it 
has to resync everything.

That's also getting near. mbox already updates the mail index when 
saving mails to it, I'll soon fix it to update cache file as well. I'll 
do the same for maildir soon too.
