    Sorry, I must have been asleep when I wrote that...

    I was expecting the implementation to copy each table separately and
    store them in a list (since this would allow easy dynamic removel of the
    entries too), hence when I saw the assignment to a single global, I
    assumed it was just over-writing it; I guess I didn't even look at the
    realloc above or noticed that it was assigning "tmp" not just the caller-
    supplied parameter:-(
