Ubuntu eating resources

Trackerd: every now and then (for no visually apparent reason), the fans on my Acer laptop kick in. If I look at the running processes with top, trackerd is right there at the top of the list sucking up my CPU resources.

This is a new feature of the O/S that I don't use. It would be nice if this process only ran when nothing else was running. After googling around, I discovered that there is a ~/.config/trackerd/tracker.cfg file that allows you to configure this application. Lots of great configuration options. Rather than throttling the indexing process back to 20, I just set "EnableWatching=false" to prevent watching of any kind.
