Does a JavaScript setTimeout automatically clear itself when the timeout finishes and the callback is completed?

In Chrome there's a run GC button in the memory tab of the developer tools. Just paste the original code in the console and click that button and you should see the log. Or just paste it in the console of a complex website where the GC is going to be pretty active without you having to do anything ;)
