If I understand correctly, this fixes the flat-file seen implementation, but
not the underlying problem, which is that updates to seen are deferred until
the connection is closed.  Am I following?  If so, is there any chance of
updating more frequently in a future release?  OE is certainly a popular
client, and it sounds like Mozilla has the same problem.  I can duplicate
this at will in OE with a skiplist seen db.
