Here is my code: 
    my $child = my $parent = my $pid = undef;

    # Create a socket pair from IPC (both ways)
    if (!socketpair($child, $parent, AF_UNIX, SOCK_STREAM, PF_UNSPEC))
+ {
        die "socketpair failed: ".$!;
    }
    else {
        # Flush messages immediately
        $child->autoflush(1);
        $parent->autoflush(1);

        if (!defined($pid = fork())) {
            die "Fork failed: ".$!;
        }
        elsif ($pid == 0) {
            close($child);

            # Here the process will carry out the work, and also write
+ to the 'pipe'
            # It will only exit this loop upon SIGTERM

            # Close the pipe with the parent
            close($parent);
            exit 0;
        }
        else {
            close($parent);
        }
    }

The pipe signal only occurs after a long period of inactivity on the client side, not on the server side (which also uses the 'pipe' to send messages to the client)
