Description
From an internal mail conversation titled "Terminal is always ticking":
> I notice that Terminal on my machine is constantly ticking, meaning XAML Tick. It looks like there is a DispatcherTimer constantly running, even when the app isn't in the foreground and even when it is minimized.
We should stop any DispatchTimers when Terminal is minimized.
