At first I also thought this to be useless, but a possible application 
just came to my mind: Imagine you run a program in parallel, and one 
process throws an exception. How do you recover consistently on all 
processes? One solution might be that the catch() clause broadcasts the 
exception to all other processes, using serialization to transmit the 
exception object.
