I noticed this as well, after installing GNU PSPP, clicking Help>Reference Manual, and then quitting. "yelp info:pspp" showed 100% in gnome-system-monitor. After killing yelp, then repeating what I did above in GNU PSPP, yelp showed up again, but wasn't using any CPU, and exited after I quite PSPP. This is on natty (Ubuntu 11.04) on a Core2 Quad core.
