Well, to my mind, making the regression tests faster is something that
could be quite helpful during beta, because a lot of people will be
running them. (Or so we hope, at least.) If the fact that e.g.
the recovery tests take a lot of time discourages people from running
them, that can't be a good thing for beta purposes. So I respectfully
reject your opinion about what I should be working on.
