// The Module object: Our interface to the outside world. We import
// and export values on it, and do the work to get that through
// closure compiler if necessary. There are various ways Module can be used:
// 1. Not defined. We create it here
// 2. A function parameter, function(Module) { ..generated code.. }
// 3. pre-run appended it, var Module = {}; ..generated code..
// 4. External script tag defines var Module.
// We need to do an eval in order to handle the closure compiler
// case, where this code here is minified but Module was defined
// elsewhere (e.g. case 4 above). We also need to check if Module
// already exists (e.g. case 3 above).
// Note that if you want to run closure, and also to use Module
// after the generated code, you will need to define var Module = {};
// before the code. Then that object will be used in the code, and you
// can continue to use Module afterwards as well.

This is a test of running out of memory in emscripten.
Chrome crashes every other refresh if the total memory size is 512mb, although 384mb seems to be stable.
Sizes around 465mb seem to crash occasionally but not necessarily every other refresh.
Firefox is very stable and allows total memory sizes up to the theoretical maximum of 2047mb without crashing.
This was tested on a MacBook Air with 4gb of RAM and Chrome 32.0.1700.68 beta.
