I would have thought it is always blocking, since it at least has to change tasks to tcpip_thread and back again? Of course, it depends on the definition of 'blocking'... However, I don't know if we have a completely nonblocking send that just puts the data on a queue... For that, we would have to support sending pbufs with TCP (in contrast to data pointer as it is now).
