That is, everything we read in the last socket.recv() call is a part of that message.

In our new setup, we'll be reusing the same connection to send an indefinite number of messages, and these won't be synchronized with the chunks of data that we will pull from each socket.recv(). Hence, it's quite possible that the data from one recv()
