The patch looks good to me (I would even claim this could go in as an independent cleanup, not tied to the RFCish nature of the later patches), though I have a question: How did you select 0x0008 for USED, i.e. does it collide with other flags (theoretically?), and if so how do we make sure to avoid the collusion in the future?
