Actually, my original code went a step further than this. It combined
all the ring data into 1 object, and then used a mini allocator for the
pipe control, ring status, and the few dwords I need. I was _sure_ you
would hate that, so I went to this.

Can you swallow the one object for everything + allocator idea?
