        Implement userIdleTime() for Windows, and place a band-aid over other
        platform implementations of userIdleTime().  This will fix the issue
        of indefinitely postposing releasing pages from the PageCache
        on non-Mac platforms, causing us to hang onto just about everything
        else about a web page.
