But is that really what we want (an bug free)? If so, we would really 
need a compile-time check that TCP_WND is at least 2*TCP_MSS (or only 
greater than TCP_MSS?) to prevent problems: If, in Jan's case, the 
remote side was lwIP, too, the connection would stall as the window 
would never reopen because the remote side wouldn't be able to send a 
2-byte-segment. I know we can fix this in lwIP, too, but there might be 
other embedded stacks having a problem with this?
