Well, I think it's mostly about valgrind making everything really slow.
Since we have seen some passes from skink recently, perhaps there was also
a component of more-load-on-the-machine-than-usual. But in the end this
is just evidence for my point that regression tests have to be very much
not timing-sensitive. We run them under all kinds of out-of-the-ordinary
stress.
