> This would enable non-blocking DNS queries. One use case is during TLS peer
> certificate verification, we need to perform a reverse DNS lookup to get the
> peer's hostname. This blocks the event loop thread!
> Some options:
> (1) Linux provides {{getaddrinfo_a}}, however I don't see an equivalent one
> for {{getnameinfo}}:
> http://man7.org/linux/man-pages/man3/getaddrinfo_a.3.html
> (2) A popular library is c-ares (MIT license):
> https://c-ares.haxx.se/
> (3) ADNS (GPLv3):
> https://www.gnu.org/software/adns/
> (4) c-ares has a list of other libraries:
