Unordered queues. A folder is an unordered queue, so if order is not vitally important, processes can communicate simply by passing memos through a folder. In fact, in all current implementations, if a folder is being used as a queue between two processes, the consumer will retrieve memos in the same order the producer inserted them, but to allow for a datagram implementation, FIFO order is not required.
