Instead of changing `registerFd` it adds an additional variant `registerFd'` which allows the user to specify a lifetime.
That being said, I'm personally not terribly fond of adding these sorts of backwards compatibility variants unless really necessary. Given that this is such a low-visibility interface we may want to consider just modifying `registerFd` and avoid further polluting the namespace (this would be the third exported variant of `registerFd`).
