Well stopping script execution from within native code is simply a
matter of returning JS_FALSE and somewhere stroring information that
this was not a real error:

  static
  JSBool
  ejs_exit(JSContext *cx, JSObject *obj, uintN argc, jsval *argv, jsval
*rval)
  {
    [...]
    exiting=true;
    return JS_FALSE;
  }

Now additionally you want something like an interrupt mechanism.
Didn't try it myself yet but it seems registering a callback via
JS_SetBranchCallback
http://www.sterlingbates.com/jsref/gen/api-JS_SetBranchCallback.html

is the suggested method
