One sender thread per client. Requires loads of resources. Kind of hacked, because the internal dependencies are very ugly now. Requires loads of testing. A problem might be the last packet sent by the server to a specific client before closing the connection, for example an error message. It might never even reach the client, because the sender thread is terminated before. I have not yet found a good way to fix this.
