No. Sometimes it will need to wait for space in the send queue. It
will, I think, always be non-blocking if you know the send queue is not
full.
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).
