This is used as a playground for me to test TPL concepts. Currently, this example shows 3 buffer blocks linked to a batch block. The batch block is then linked to an action block. Once each of the buffer blocks has posted a Tuple<string, string> object, the batch block will create an array of tuple<string, string> objects and send that to the action block. The action block will print the results of the batch. There are random delays inserted througout to simulate delays in an actual program. The example clearly shows the 1 and 2 buffer blocks filling up while the 3rd buffer block is always empty.
