Using POSIX message queues (mq_overview), play "hot potato" between six processes. The original process sends out a message once it has generated five child processes. Each process, excluding the original, attempts to grab the message before again posts it on the message queue. Count the number of messages received by each process and declare the first process to receive one thousand (1,000) messages as the loser.
