This failure is pretty rare.
* The first failure happened on 2022-09-13 on my desktop (fg-deb64). There is
no trace of it happening on the previous 3 months.
* Another failure happened on 2022-11-18 also on fg-deb-94.
* And it happened on the GitLab CI, impacting MR!1669.

ws2_32:sock has a similar failure which started in September (see bug 54074).
