I'm not exactly clear on how he's using coroutines to handle async callbacks. Can anyone help explain it?

  Sure. I basically take the async callback and wrap it in a coroutine before I invoke it. If the coroutine yields back a function, I assume that that function can be repeatedly invoked until it returns a truthy value indicating it wants to resume. Unfinished coroutines are then kept in a table, and after each event from the ComputerCraft environment, I check the table of unfinished callbacks to see which ones can be resumed.
