RESUMO

Multithreading has become popular as a way to organize concurrent tasks and achieve better performance from CPUs. However, programming with threads is not an easy task. Usage of shared resources needs to be coordinated because concurrent access to them, in most cases, may create inconsistency in the application. The event-driven model has been pointed as a good alternative to multithreaded programming. In this model, a task is performed by one or more events, where a main loop is responsible for receiving and dispatching these events. In this work, we investigate a model to combine event-driven and preemption in Lua without bringing back all the concurrent programming problems. We also investigate how the language¿s characteristics can be used to provide flexible coordination mechanisms. These characteristics can aid, for example, to create new mechanisms based on the ones already existent.
