It will block in start until a child ends.

By the way, 

for my $command (@commands) {
    $manager->start and next;
    ...
    system( $command );
    $manager->finish;
}

is better written as 
for my $command (@commands) {
    $manager->start and next;
    ...
    exec( $command );
    $manager->finish;
}

[download]

since all finish does is end the process.
