OK, don't do this at home, but even so, this shouldn't permanently 
disable the system...
Using Squeak 4.1 + Seaside 3.0:


myWindow := (SystemWindow labelled: 'test') openInWorld.

myArray := Array new: 10.

"add zero or more morphs to myArray, but less than myArray size"
myWindow addAllMorphs: myArray.

"squeak stops working..."
