Comment:
In general, it is mostly a problem on musl because musl passes O_NONBLOCK to fcntl().
On glibc, this is (usually?) not the case, so the bug won't be triggered there.
Only because the bug was not triggered as reliable before doesn't mean it's not there.
Patching the esr versions won't hurt, not sure if we need rebuilds, we could also do it with the next round of minor bumps
