PUBLIC MARKS from nhoizey with tag timeout

There's a handy technique I picked up from Twisted Python that I like to call polite loops. Polite, because sharing resources in an environment like a browser takes tact. When you're at a party with an open bar, you don't hog the bartender's attention, downing pint after pint while he's force to wait on you to have your fill. You're polite; you get your Newkie Brown and walk away so someone else can order.
