Yes, I expect that to help a lot.

I said very clearly in my previous email that "I think that everyone
is prepared to accept a limited amount of further delay in pressing
forward with the main part of sync rep".  In other words, I think
everyone is willing to consider your ideas provided that they are
submitted in a form which everyone can understand and think through
sometime soon.  I am not, nor do I think anyone is, saying that we
don't wish to consider your ideas.  I'm actually really pleased that
you are only a day or two from having a working patch.  It can be much
easier to conceptualize a patch than to find the time to finish it
(unfortunately, this problem has overtaken me rather badly in the last
few weeks, which is why I have no new patches in this CommitFest) and
if you can finish it up and get it out in front of everyone I expect
that to be a good thing for this feature and our community.

I was thinking about that earlier today.  I think it's definitely
possible that we'll need to do some benchmarking, although I expect
that people will want to read the code first.
