You might as well keep testing the old one, if that gives it better
coverage. No need to disrupt anything you already have running.

The more important input is "was that actually the root cause", rather
than deciding between the ugly or clean way of fixing it.

So if the first patch fixes it, then I'm pretty sure the second one
will too - just in a cleaner manner.
