It's from control theory. In an open loop control system I just send the
system messages to tell it how to behave, whereas in a closed loop system
I get messages back so I can check that it's doing what I want. Think of
the difference between a simple mixer tap and a thermostatic mixer.

Open loop:

  +----+                  +-----+
  | Me | --- message ---> | You |
  +----+                  +-----+

Closed loop:

  +----+ --- subscription from ---> +-----+
  | Me |                            | You |
  +----+ <---- subscribed to ------ +-----+
