event loop for Lua (development package)
cqueues is a type of event loop for Lua, except it's not a classic event loop. It doesn't use callbacks—neither as part of the API nor internally—but instead you communicate with an event controller by the yielding and resumption of Lua coroutines using objects that adhere to a simple interface.
