Do related frames and windows share the same JavaScript execution queue?
<p>If I have a <code>frameset</code> with 2
   <code>frame</code>s does each frame have its own
   JavaScript execution queue, making
   the window "multi-threaded"? </p>

<p>What about <code>iframe</code>s?</p>

<p>What about child windows?</p>

<p>When I say "execution queue", I'm talking about the same queue used to queue up timers and other events.</p>

<p>The reason I ask is because that I'm wondering if you can run into any multi-threaded-type issues when accessing contexts of scripts in other frames or windows.</p>
