The wait/notify capability is used for announcing that more memory is available or that a new message is available. This isn't necessary for the locking protocol in itself, we could also repeatedly take the respective locks and look at the data in order to determine the state of the system. Wait/notify simply allows us to yield the thread in the cases of a full buffer or no messages being available for printing.
