[Catalyst] How to run self-tests from within the application

[Ashley]

What am I doing wrong?

This code starts to work but hangs (and always times out if a timeout  
is specified).

sub auto :Private {
     eval { require IPC::Cmd;
            require File::Find::Rule;
        };
}
sub index :Path :Args(0) {
     my ( $self, $c ) = @_;
     my @tests = File::Find::Rule->file()
                      ->name( '*.t' )
                      ->in( $c->path_to("t") );

     # Messing with this doesn't seem to help...?
     local $SIG{CHLD} = "DEFAULT";

     my $prove = IPC::Cmd::can_run("prove");

     # Just run 01app.t in $test[0] for the sake of testing this.

     my ( $success, $error_code, $full_buf, $stdout_buf, $stderr_buf ) =
         IPC::Cmd::run( command => [ $prove, "-I" . $c->path_to 
("lib"), $tests[0] ],
                        timeout => 15,
                        verbose => 0 );

     $c->response->content_type("text/plain");
     $c->response->body( join"\n", @{$full_buf} );
#    $c->response->body( join"\n", @tests );
}


After it times out, this appears in the test server output in the  
terminal:

.../t/01app......ok
All tests successful.
Files=1, Tests=2, 23 wallclock secs ( 0.02 usr  0.01 sys +  3.78  
cusr  0.57 csys =  4.38 CPU)
Result: PASS

Why is it hanging? Is there a pipe or something I could add to the  
command? What are the environmental caveats if I can get this to run  
under the test server v fastcgi/modperl?

Thanks for looking!
