+ * The particular require runtime that we are using looks for a global
+ * `ErrorUtils` object and if it exists, then it requires modules with the
+ * error handler specified via ErrorUtils.setGlobalHandler by calling the
+ * require function with applyWithGuard. Since the require module is loaded
+ * before any of the modules, this ErrorUtils must be defined (and the handler
+ * set) globally before requiring anything.
+ *
+ * However, we still want to treat ErrorUtils as a module so that other modules
+ * that use it aren't just using a global variable, so simply export the global
+ * variable here. ErrorUtils is original defined in a file named error-guard.js.
