Description James Su 2009-03-09 20:05:12 PDT 
When running a piece of javascript code by using JSEvaluateScript() or JSObjectCallAsFunction(), the native code might be blocked because of dead loop or some other abnormal things in javascript code. In this case, a mechanism to let native code be able to interrupt the javascript code by throwing a javascript exception would be very useful.

A simple solution would be: Provides an API to let C++ code register a callback to JavaScriptCore, then this callback will be called after certain number of javascript instructions have been executed.

SpiderMonkey has similar feature, see:
