Kieran, I studied Jans wireshark logs and indeed it looks a little 
strange that the window doesn't open unless it reaches 0, although lwIP 
was sending ACKs all the time. Is this an intention of the window update 
threshold mechanism? I thought it was only to not send (duplicate) ACKs 
that only contain window updates, not to prevent window changes at all?
