No, outgoing packets are sent from the same thread that processes incoming 
packets. Either they are sent as a direct reaction to incoming packets (i.e. 
sent from the same call stack) or application threads can use tcpip_callback() 
(or any other mechanism if you want to implement it on your own) to get into 
the input-processing thread to send packets (or invoke any other 
non-threading-protected lwip function).
