What kind of bugs does this really solve?

DNS servers that can only process one request per client at a time?

I mean, our intention is certainly to make things work by default,
without any manual configuration, and this glibc option is something
I'd really not like to replicate in resolved I must say.

but before we can see what we can do on this, I'd really need to
understand what kind of broken DNS servers this is really supposed to
