This is so that we can use the exit code as a boolean value in the
parent without having to invert it.  Given that this is just a fork() of
the program itself it didn't seem useful to invert the value purely to
pass it back to the parent, it seemed better to consistently use natural
true/false rather than 0 on success rather than mixing the two.
