I don't see anything unusual in top. The spike is so quick, it's
literally a straight up line in gkrellm, just every 5 seconds.

I'm not sure what else I can use to monitor this. I wouldn't even know
about it if gkrellm hadn't shown it to me. It doesn't affect performance
really, but it's annoying to know it's there.

any other ideas are welcome.
