docs: When we get our expected message response. Save the message object, and notify the waiting thread
  that the message is now available to be passed back.
  This method attempts to handle and warn against cases where multiple messages came in, or a message
  came in after the timeout period.
  @param message Message response from the project board that will be saved.
