+ * This version of PollQ. c is for use on systems that have limited stack
+ * space and no display facilities. The complete version can be found in
+ * the Demo/Common/Full directory.
+ *
+ * Creates two tasks that communicate over a single queue. One task acts as a
+ * producer, the other a consumer.
+ *
+ * The producer loops for three iteration, posting an incrementing number onto the
+ * queue each cycle. It then delays for a fixed period before doing exactly the
+ * same again.
+ *
+ * The consumer loops emptying the queue. Each item removed from the queue is
+ * checked to ensure it contains the expected value. When the queue is empty it
+ * blocks for a fixed period, then does the same again.
+ *
+ * All queue access is performed without blocking. The consumer completely empties
+ * the queue each time it runs so the producer should never find the queue full.
+ *
+ * An error is flagged if the consumer obtains an unexpected value or the producer
+ * find the queue is full.
