Yes, if they take more than a second to run.

We've already made this decision with all the tests previously marked as
expensive, so there's nothing new here.  We are formalising what counts
as a "too slow" test for the default "make check" case.

We could add more levels -- we now only have "normal" and "expensive",
right?  We could add an in-between level, "quite-expensive" or whatever.

I do that, too, when working on something specific.  But being able to
say "make check" gives me greater confidence that I've not messed up
something in a related area (and let's face it, the entirety of Emacs is
"a related area" :-)).
