On one of my system im really concerned about the ram usage.
But mostly its because i dont like to waste resources. It just nags me
having a perl script running that uses twice the memory as the window
manager just to display some status information. And it adds up. 2 for
the status, 6 for a python based notifier, maybe a wallpaper changer or
a udev daemon...
