Doesn't sound like the threading is the cause of this.

FINs are only sent when tcp_close() is called, I think.  Might be worth
you adding a few printfs to see what the call path to here is.  

Also, I notice that by default (if LWIP_CALLBACK_API is set) the tcp
pcb's recv callback is set to tcp_recv_null() which will close a
connection if no data is received.  It might be worth checking that this
isn't causing you problems.
