AFAIR it was the test runner hanging after all tests are done. -- Best regards, Michał Górny

RCs are our chance to get upstream fixes into the release. If we skip them, it means we'll end up having to backport everything ourselves. It's a loss for us, and it's a loss for other people using LLVM. Plus, filing bugs as "release blockers" has a certain psychological effect. > > > > > 6.

If infra work means writing batch scripts to drive build bots, automate tasks, generating reports and sending email notifications, it fits summer of code.
