Greetings fellow monks!

I have an application that forks off a continually-running child process. In the course of the child's life, it frequently shells out to run different applications. As a result, it will sometimes disregard signals (INT and HUP) if the signal is sent while the child is in one of these processes.

Is there a way to correct this behavior? I would like it to wait for the forked application to complete then perform whatever the signal requires. Can I only do this by forking another child process to execute the system command?

Here is how I'm handling the interrupt now:

$SIG{'INT'} = 'stop_child';

sub stop_child{
    print "Recieved stop signal.\n";
    exit;
}
