Blocking call in connection/receive_data.

[tacozMacleo]

I do not like blocking calls, that that can not be close gracefully.
So in Class: ReceiveData function: receive_data, we have a socket.recv,
that need to be changed, so it can be closed gracefully.
Example on how:

If you have a nicer way, great then use it.
