Follow-up Comment #3, task #6683 (project lwip):

Sockets generally can't be used in from more than one thread, for now: a
socket has a netconn nad that netconn's mbox is used to tell the application
its request to tcpip_thread has finished. Thus, if you call socket functions
from 2 or more threads at the same time, it won't be clear which request has
finished when tcpip_thread posts to sock->conn->mbox.

This is something I'd like to see changed, though :-)
