.. but I waited to merge it until I had time to review it more
closely, because I expected the review to be painful.

I'm happy to say that I was overly pessimistic, and that instead of
finding things to hate, I found it all looking good.

Particularly the whole "use reference counts properly, so that
lifetimes make sense and all those nasty cases can't happen" parts.

It's all merged, just waiting for the test-build to verify that I
didn't miss anything (well, at least nothing obvious).
