Question: Paranoid Pirate Pattern auto re-connect for workers and clients on queue restart

[vxmark]

This question is related to the Paranoid Pirate Pattern sample project:

Is it by intention that the Paranoid Pirate Pattern is not supposed to recover from a restart of the Queue component or is this an error of the sample implementation (or even NetMQ core) which needs to be fixed?

Steps to reproduce:

1. start queue
2. start a worker
3. start a client
4. stop queue
5. wait for a timeout message of worker and/or client printed to console
6. restart queue

After these steps messages from clients wont be processed anymore despite all components (queue + worker + client) are up and running again after step 6.

Problem located inside the worker component.

On every (heartbeat-) timeout inside the worker it will completely dispose the DealerSocket and then create a new one. But for this newly created DealerSocket the event wireup for ReceiveReady is missing. This way the new DealerSocket won't react to any incoming messages.

For reproduction of the actual error I would recommend to disable the "crash simulation" inside the worker component. This simulation will most probably fire before one is able to see the actual error which I am addressing with this issue / pull request.
