Now i feel like i'm walking on very thin ice.

You suggested to set $pm->set_waitpid_blocking_sleep(0);  # true blocking calls enabled.

After setting this in my/your script it seems as it behaves like as expected, right?

You suggest to switch sleep for select( '','','', $timeout ).

I assume that you refer to line 782 of the sources:

sub _waitpid_blocking {
    my $self = shift;
 
    # pseudo-blocking
    if( my $sleep_period = $self->{waitpid_blocking_sleep} ) {
        while() {
            my $pid = $self->_waitpid_non_blocking;
            return $pid if $pid;
 
            sleep $sleep_period; # should be line 782
        }
    }
 
    return waitpid -1, 0;
}

The author names it $sleep_period instead of $timeout.

Do you mean that sleep $sleep_period should be replaced with select( '','','', $sleep_period )?

I'm sorry if it looks like i got a true block. Please correct me if i'm wrong.

Update: Do'h! It's too late tonight!

Edit: No reason to complain.

Thank you very much for further advice and best regards, Karl
