I have a script that runs a test on a list of test_objects. These tests all run concurrently using threads. Should a test fail at anytime, I would like to stop all other running threads and safely exit out of the program. 
sub test1252 {
    my @jobs = ();
    foreach my $test_obj (@objects) {
        push @jobs, async {
            my $rc = test($test_obj);
            if ($rc ne 0) {
                print "Test Failed for $test_obj\n";
                local $SIG{'KILL'} = sub {threads->exit();};
                $_->kill('KILL')->join() for @jobs;
                exit $code_blue;
            }
        };
     }
     $_->join for @jobs;
}

I get something like this using 'kill' with the handler 
Perl exited with active threads:
        9 running and unjoined
        0 finished and unjoined
        0 running and detached

It doesn't appear that all the threads have died upon program exit, so I'm sure I'm not doing something right...
