Abstract:In this paper we introduce a new method for pessimistically implementing composable, nestable atomic statements. Our mechanism, called shelters, is inspired by the synchronization strategy used in the Jade programming language. Unlike previous lock-based pessimistic approaches, our mechanism does not require a whole-program analysis that computes a global lock order. Further, this mechanism frees us to implement several optimizations, impossible with automatically inserted locks, that are necessary for scaling… Show more
