I have no plans on changing how seen state is currently cached. We haven't 
had any complaints from our users and (now that we found the cyrusdb_flat 
problem) it doesn't seem like it is that huge an uissue for most other 
sites, either.

The only time I can see this changing is if someone decides to abstract out 
all flags equally so that we can have shared seen or private deleted flags, 
etc. How flags are written back would be an obvious thing to add to such a 
project.
