I completely agree with you! Here's an example of what you mean below. If control-c is captured when asking for input, then script will crash. However, if control-c is captured during output, everything goes as expected... I guess I am just breaking stdin and it does not know how to get back there... I'm not sure how in my own code to remedy this, since there are a lot of prompts, all broken by output. 
#!/usr/bin/perl -w

$SIG{'INT'} = 'catch_int';
sub catch_int {
    my $int_ans;
    system("\n");
    while ($int_ans !~ /[Nn]/) {
        print "Do you want to exit [y or n]? ";
        $int_ans=<STDIN>;
        if ($int_ans =~ /[Yy]/) {
            die "\nCaught SIGINT -- Program stopped by user\n";
        }
    }
}

print "Please enter a choice: ";
chomp(my $choice=<STDIN>);

if ($choice =~ /[A-Z]+/i) {
    for (my $i = 0; $i < 10000; $i++) {
        print "Good choice!\n";
    }
}
