Thanks. The post you referenced gets me started. Right off, I have one question. How do I install signal handlers for each of the threads? A situation may arise where I have to kill everything. Hopefully not the hard way.

I'm under the impression (possibly falsely) that I need to kill the $pid for mysqldump to ensure that the thread is joinable. I'm not sure how to do that when dealing with multiple threads. 

my @signals = qw(TERM ALRM INT HUP);
for (@signals) {
    $SIG{$_} = sub {
        $rt->debug(qq{Caught signal: $_.\n});
        kill 9, $pid;
        $thread->join();
        exit;
    };
}
