And I just demonstrated it. Strangely enough, sending from Windows 
(where the dos say "send returns the total number of bytes sent, 
which can be less than the number indicated by len") it always 
sent the whole buffer, even when that was 1M on a non-
blocking socket. (I select()'ed the socket first, to make sure it 
could send something).

But from Linux, the largest buffer sent was 54,020 and typical 
was 27,740. No errors.
