Good point.

I'll address that in the DESIGN.md in the next rev.

Separately, it's looking like xact streaming is possibly more complex than
I hoped due to cache invalidation issues, but I haven't been able to fully
understand the problem yet.

The other thing is that I think we don't need the "forward_changesets"

Removed, change pushed.

Also pushed a change to expose the decoded row data to row filter hooks.

I won't cut a v4 for this, as I'm working on merging the SGML-ified docs
and will do a v4 with that and the above readme change once that's done.
