Unreliable test timings! On an initial run, this test took 1058.10ms, which exceeded the deadline of 500.00ms, but on a subsequent run it took 0.08 ms, which did not. If you expect this sort of variability in your test timings, consider turning deadlines off for this test by setting deadline=None.

do you mind merging master and pushing, so the CI reruns then?
