 +===== Saving memory =====
 +  * 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.
 +  * The cost of require or dofile is relatively small, so break your program into overlays one per event and use a small stub function as a callback to load each.
 +    * Use compiled .lc files and load using dofile().
