Good point -- I meant send(). I keep forgetting that the libc socket
write() operation is missing in Python and only the send() call has
been made visible. In C write() and send() are effectively the same
thing (the parameters are arranged a little differently, but they
behave identically otherwise).

No, I wouldn't exect that.
