        My original email needs clarification: I'm not asking about the
Updates work; I'm asking about the issue of changing the buffer cache
locking mechanism to support upcoming changes in Soft Updates. I've been
exchanging email with FvdL regarding Soft Updates for a while, but he
suggested that I send email here about the buffer cache locking issues.
