[Debugger] Stop re-running all the issues and hope they pass.

This maybe was needed in the past, but we're moving to a model
where we really want to control what's failing and why. If something
fails, stop re-running. Instead, try to get a proper blame
mail and investigate. This might be a little shaky in the
short term but I'm confident it will go a long way.
