title: Interrupt execution of v8 script inside native function
body: <p>I use v8 and spidermonkey from C++ programs. In spidermonkey it is easy to stop the execution, you just return FALSE in any of native methods you implemented in C++.
  But I fail to see how to do the same thing in v8.</p>
  
  <pre><code>Handle&lt;Value&gt; enough(const v8::Arguments&amp; a) {
      // want to tell v8, that execution is not needed to continue.
      return v8::Undefined();
  }
  </code></pre>
  
  <p>maybe return something specific, or set some variable, or call v8 function, or send a message, or throw and exception, any idea?</p>
