does not return 0 if anything fails (useful for Jenkins)
Fixed regression introduced by commit 7c849dd8e8cae590a127b49f5831943f79f80343
We need to add +1 to the string size to have the correct message size (\0)
Updated tests as the serialization has changed
zmq: remove crufts (mockZMQ/ZMQHelper)
zmq: remove now useless workaround since it breaks LazyPirateClient unit tests
zmq: fix class Server serialization/deserialization and associated unit tests
zmq: now we use ExecConfiguration to parse configuration files in diet_initialize which
returns an UserException instead of SystemException
