Why is "chrome frame" in the name? Why not just "shutdown-delay"?

Because this applies only to Chrome Frame. It is used in the
ChromeFrameAutomationProvider, which is only used when Chrome Frame is in the
picture (see earlier review comment). 

I considered making it generic and adding it to AutomationProvider, but that
would require a little more plumbing and I don't have a use case for it.
