[zeromq-dev] zguide: Text doesn't match example and problem with "Hello World" example

[Pieter Hintjens]

Hi Moritz,

Thanks for the feedback.

> 1) The first example at http://zguide.zeromq.org/chapter:all#toc31 uses
>   zmq_device although the text above it refers to zmq_queue.

Fixed.

> 2) The "Hello World" example at
>   http://zguide.zeromq.org/chapter:all#toc4 behaves differently with
>   trunk ZeroMQ (2.1?) than with the latest stable version (2.0.10)

0MQ/2.1 blocks if you terminate a context with open sockets, in a
single thread.  I've added a zmq_close for the socket.  There are lots
of examples affected by this change, I've fixed them all, hopefully.
