title: Selenium2 (Grid): Violently killing a browser session
body: <p>Some browsers like IE fail to close when calling webdriver.quit() if they a modal javascript alert is displayed at the time of closing.</p>
  
  <p>Does Selenium2/Webdriver have a way of killing the browser off in such cases?  If such an occurrence happens, it messes up all subsequent tests on that browser.</p>
  
  <p>Regards,</p>
