You haven't sent a packet capture of that case yet.  My best guess for
that is that the last ACK gets lost, and then both sides are waiting for
the other.   lwIP should probe the other end in that situation, but the
code to do that was relatively recent (just before 1.3 I think) and
there may still be some issues with it.
