Must get my head around what it is doing now. 

$SIG{ INT } = sub  {
     ## State makes $last a closure; that is a variable that remember'
+s its value 
     ## between invocations of the subroutine
     state $last = 0; 

     ## if the time now is greater than 2 seconds later than the last 
+time we saw a ^C
     if( ( time - $last ) > 2 ) {
         ## Overwrite the last time with the current time
         $last = time;
         ## And just return; ignoring this ^C
         return;
     }
     ## However, if it is less than 2 seconds; die.
     die 'Interupted by ^C^C';
};
