Agreed. I've tried to do a quick review and give early feedback on the
big patches, concentrating on high-level, architectural issues, so that
authors of big patches don't need to twiddle their thumbs waiting for
review.

OTOH, more detailed review at early phase is not a very good use of time
if there's design issues to be resolved, and author is still working on it.

I don't have suggestions, but I'd just like to say that you Robert, have
given extremely valuable feedback. And on many patches too, I have been
very impressed throughout the commitfest. Thank you!

I'm not sure how much round-robin-review has taken load off committers,
you have to read and understand a patch before committing anyway. It has
helped, for sure, but not dramatically. However, I think that it has
made a big difference from authors point of view; you get feedback earlier.
