Must be poor timing. First DNS took forever, then I get unable to
connect, connection time-outs...

BIO would be an overkill in the original context, i.e. in context for
irritating problem in FIPS module. But as current FIPS module is not
really supported option in HEAD and would need overhaul in either case,
let's let omission slide in HEAD. BTW, the comment was also meant to be
of a little bit more general character, i.e. just because something is
not used by the library itself, it doesn't have to be useless.
