The v13 package builds that are running every 6h here haven't seen a
problem yet either, so the probability of triggering it seems very
low. So it's not a pressing problem. (There's some extension modules
where the testsuite fails at a much higher rate, getting all targets
to pass at the same time is next to impossible there :(. )
