The separate programs that make up a Linda ensemble
all float within a region called 'tuple space'.
They are a fleet of ships and tuple space is the sea,
or a flock of helium balloons and tuple space is the sky,
or a herd of wontons and tuple space is the soup.
When one program has information for the others,
it wraps it up and jettisons it -- sets it adrift in tuple
space.
