    theme-adium: keep count of the pages loading instead of using a boolean
    
    Each time theme_adium_clear() is called, WebKit has to reload the page. If we
    do multi calls to clear() in a short interval, we used to think the page was
    loaded while it was the *old* one which was actually loaded. (#645670)
