- The "thin-air problem" is a major open problem in programming-language semantics: currently no mainstream language that aims to support high-performance concurrent code has a satisfactory definition, as it has proved very challenging to define an envelope of allowed behaviour that admits established hardware and compiler optimisations while still ruling out values appearing "out of thin air". This paper introduced a potential solution that remains (among several proposed in the literature) the most liberal in terms of the optimisations that it admits.
