OK, but that's in the past now - good. I thought Tom was saying that
it might need to be done again.

I agree. It's possible that this might change in the future - git has
come a long way in a short time. But I'm not betting on it.

I think the problems it would solve for us are (1) emailing huge
patches around sucks (it sucks unnecessarily because of the
mailing-list size limit, but even if someone fixes that, it still
sucks), (2) no need for a CVS-to-GIT conversion that may incur dirty
reads; (3) retention of history and authorship when merging patches
into core. It's possible that it might change our workflow in other
ways too, but even if we got only those three things I think that
would be pretty nice.
