reset() should work _before_ the Head block reaches the specified items,
but once it reaches that number of items, Head is done and the flowgraph
will terminate. So, I don't think reset() will do what you're hoping.
Also, the code you posted creates a _new_ Head block each time through the
while loop and resets that block. You would want to operate on the Head
block in your flowgraph.
