Where do you print $pid? You declare two variables $pid in two places:

$pm->run_on_finish( sub { my ($pid, $exit_code, $ident) = @_; $tmpFile
+s[$ident] = undef; } );

Here, $pid is likely the PID of the child that just terminated.

my $pid = $pm->start($i) and next;

Here, $pid will always be 0 after the next statement. Maybe you want something like this:

my $pid = $pm->start($i);
if ($pid) {
    print "Launched child $pid\n";
    next;
};
