The socket is typed the way it is because of these two functions:
val subscribe : sub t -> string -> unit
val unsubscribe : sub t -> string -> unit
Meaning that you should only be able to use subscribe and unsubscribe on sockets created with type sub Socket.t ('a = sub).
This reminds me an example with phantom types I saw somewhere, possibly in the context of Xen and its OCaml bindings.
This is where you can only use certain functions that access memory on memory that has been initialized.
Maybe phantom types are called for here.
