I see this misconception all the time. "top" does not indicate how much
CPU load a process causes. It indicates the *relative* CPU load of *all
the processes currently running*.
If you SSH into a machine that's only running a screen saver, it'll
always show the screen saver using up a big chunk of the CPU--because
the screen saver is about the only thing using any CPU! I mean, 'echo'
will take up 40% of the CPU if the machine is otherwise idle...
To find out if your screen saver is actually a CPU hog you need to use
the profiling tools from the Developer Tools.
