Steps:

   - Pulled down the 


Problems:

   - All the RemoteRequestServiceTestCase.cs tests fail, due to StubSocket 
   not being castable to Socket
   - Tests "*when_recvTimeout_recv_should_return_null", "creating_pub" *and
   * "creating_sub_and_subscribing_to_specific_weird_topic"* all loop 
   forever


The culprit appears to be in 
https://github.com/castleproject/castlezmq/blob/master/src/Castle.Zmq/Socket.cs 
(The issue is in red):

                public byte[] Recv(bool noWait = false)
{
EnsureNotDisposed();

using (var frame = new MsgFrame())
{
var flags = noWait ? Native.Socket.DONTWAIT : 0;

again:   // We loop here forever
var res = Native.MsgFrame.zmq_msg_recv(frame._msgPtr, this.SocketPtr, 
flags);

if (res == Native.ErrorCode)    // It always is for the "looping" tests
{
var error = Native.LastError();

if (error == ZmqErrorCode.EAGAIN || error == ZmqErrorCode.EINTR) goto 
again;  // It's always EAGAIN

if (LogAdapter.LogEnabled)
{
LogAdapter.LogError("Socket", "Recv interrupted with " + error + " - " + 
Native.LastErrorString(error));
}

Native.ThrowZmqError(error, "Recv");
}
else
{
return frame.ToBytes();
}
}

return null;
}



Apart from the fact that these are failing, if you've set ZMQ noWait to be 
false, shouldn't *zmq_msg_recv* be blocking, rather than returning an 
instruction that you should block?

This definitely looks like the best binding available for us, and I'm 
guessing you've solved these issues internally?

Thanks for any help!
