| + | * Avoid upvalues for context passed between event callbacks, as its very difficulat to get a handle on memory leaks created by these. Only use globals for this usecase. | ||
| + | * Nil globals once they are no longer needed so that they can be properly GCed. | ||
| + | * Allocate resources and create closures on a just-in-time basis. | ||
