OK, thanks Tom, that is at least something. I would still like this to be kinda documented/guaranteed, especially if nonblocking mode is required for this behavior (which is given in my case). But I guess that's not up to me, so I'll drop the topic and I'll just have to accept the status quo.

Thanks, Daniel
