POE::Wheel::Run and sig_child

[Mike Schilli]

I must be missing something obvious, as I'm getting

    in start at ./wheel line 14.
    starting ... at ./wheel line 27.
    killing process at ./wheel line 30.
    7353: !!! Child process PID:7354 reaped:
    7353: !!! Your program may not be using sig_child() to reap processes.
    7353: !!! In extreme cases, your program can force a system reboot
    7353: !!! if this resource leakage is not corrected.

although the code catches the sig_child:

    use strict;
    use warnings;
    use POE;
    use POE::Wheel::Run;

    my $session = POE::Session->create(
      inline_states => {
          _start => sub {
            warn "in start";
            $_[HEAP]->{wheel} =
            POE::Wheel::Run->new(
              Program     => "sleep",
              ProgramArgs => [60],
              CloseEvent  => "closing",
              ErrorEvent  => "closing",
              StderrEvent => "ignore",
            );

            $poe_kernel->sig_child($_[HEAP]->{wheel}->PID,
                               "sig_child");
            $poe_kernel->sig( "INT"  => "down" );
            warn "starting ...";
         },
         down => sub {
             warn "killing process";
             $_[HEAP]->{wheel}->kill();
         },
         sig_child => sub {
             warn("waitpid for " . [ARG1]);
             waitpid $_[ARG1], 0;
         },
     });

    $poe_kernel->run();

Looks like the 'sig_child' handler is never run ... suggestions?
