wicked :)  My guess is because #perform:withArguments: is a primitive 
the infinite loop happens inside the VM when the VM tries to evaluate 
the arguments. I have no idea whether it is even possible to interrupt 
such a loop by `Alt+.` escape sequence. I'm looking forward to what 
others have to say. Thanks! Jaromir
