Yes, I've seen something very similar which as you say is very rare. It has only occurred once or twice since I installed Snow Leopard about a month ago. Far too seldom to associate it with a specific action on my part. I will note I was having another problem with Mathematica and Snow Leopard which I now attribute to a third party utility I had installed, Key Cue. That utility would produce a display of all the key board shortcuts available in a program after holding a trigger key down for a while. With Key Cue installed, I Mathematica would beep indicating an error. Mathematica acted as if I tried to evaluate something without having anything selected. Whenever this problem occurred, Mathematica's memory consumption would significantly increase. It only took a few times until several swap files would be created significantly slowing Mathematica. I've not had this problem since removing Key Cue from my system. I've also not experienced the other issue since removing Key Cue. But this may be entirely coincidental given how rarely the other has occurred.
