Cancelling the context just marks the context as cancelled. It does not actually stop any goroutines using the context. Those goroutines must themselves periodically check the context to see whether it has been cancelled, and, if so, stop working. They do that by calling either the Done or Err method; it's much more common to call the Done method (and check whether the channel is closed).
