The changeset workflow is what Gerrit uses. Gerrit is great.

There's a free service (GerritHub) that lets you use Gerrit for your public GitHub project. The learning curve for it is pretty steep if you've never used Gerrit before, though, and it does have some reliability issues. But for a certain kind of project it can really transform the code review experience.

Reviewing code on GitHub is tough, especially with larger changes. However, Gerrit's user interface is so beginner/user hostile that I would still prefer it to Gerrit. It scares away new contributors. :(
