I would also like to formalize what Simon said as another possible answer: G) Upgrading to the latest development release Although I guess when we switch over to git, developers using the repo shouldn't have a difficult time with upgrading... Actually, one last thing I just thought of, we can't completely control the rebuild time of sage since there are certain files which trigger a major recompilation. Although I've been told that one of the longest part of a source build comes from the ATLAS part, and I guess we'd always be cutting that out...
