I wouldn't expect an exception from ctrl-c. That sends a signal to kill the 
program, which normally means that you're program is killed without any 
exceptions being thrown or anything of the sort. You just get to do something 
in the signal handler if you catch the kill signal and _then_ the program 
dies. But maybe Windows does something differently. I don't know. I use Linux 
almost exclusively, and you definitely _don't_ get an exception in Linux.
