That seems really bad, so now I'm favoring (3).
I take this back--for the "average" developer 1G would still be useful, I would imagine that most branch switches would not involve many spkgs and a lot of code change. Someone who re-builds from scratch quite often (rather than upgrading) would be served by a bigger cache, but they're not (hopefully, in the new workflow) a typical developer. In this case I saw we go for option (1). There's still the issue of avoiding $HOME if it's an NFS mount, etc. - Robert -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
