Could you be a bit more specific here? I think the only problem we have is
visibility, as the swing thread locks on lock and the other threads on lock and
rows. So I think of it as a kind of eventual visibility.

That was my first thought, but it would introduce another thread. We could drop
the row locks, though.

Right. Get swing out of the path and be happy.
