Actually, that's not the real issue.

The real issue is that it doesn't work. I thought about it, and with 
multiple roots (which _can_ get merged together) it just isn't something 
that actually helps.

If you couldn't merge across roots, you could have a "uuid+generation 
header", but the moment you have multiple roots it actually gets quite 
complex.

So scratch the generation header.  It's not the answer.

And I do think that we can do it without it. I'm still thinking about how 
to do it efficiently, but I think I can get there. I just haven't had the 
time to sit down and really think it through and try out my ideas yet.
