Someone I know recently enrolled in an introductory computer science course that introduced her to the [halting problem][problem]. She also recently read Charles Stross's book _[Halting State][state]_, and was curious if that particular title referred to the halting problem.

Does anyone know if that's true, or if not, what "Halting State" refers to?
