The first permutation done in the test does a wait, a wakeup then a detach. It is proving to be unstable in the CI for FreeBSD (Windows and Linux are stable). The failure shows that the wait is so slow to finish after being woken up that the detach has the time to finish before the wait, messing up with the expected output. There may be a platform-specific issue going on here, but for now disable this permutation to make the CI runs more stable. Discussion: https://postgr.es/m/ZxrnSGdNtQWAxE3_@paquier.xyz
