    Lessen overhead of idle daemon panels
    
    Turns out having a daemon panel reacquire a lock every 0.2 seconds is fairly
    taxing, even if the panel isn't doing anything. That, and having the log panel
    every 0.3 seconds is kinda silly. This drops the log panel usage when idle by
    80% (0.5% to 0.1% on my system).
