DrScheme did this once on my Mac about a week ago.  At the time, I was  
busy, I wasn't actually using DrScheme, so I shut it down.  I'll be  
more alert and report it next time.  I'm currently running revision  
14683 (may1).

If I recall, the only thing I had done with DrScheme that session was  
to start it, press F1, look up something in the documentation on  
Safari, and then move on.

Also once in a while Safari (v4 beta 5528.16) starts eating up  
resources and I shut it down, but that happens when I'm not running
