I'm new to Haskell and have reached an impasse in understanding the behaviour of sockets.

Your question is actually not related to Haskell at all, but is a general "I don't understand socket programming" question. You're being misled by the non-blocking sockets observation - this makes no difference to the behaviour of your program. I recommend picking up copies of "Unix Network Programming" and "TCP/IP Illustrated", and reading them.
