Yep, this is the case: the silly window avoidance means we update the
advertised window only when it increases by at least one MSS.
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?
