by IP addresses, which are IPv4, therefore IPv6 is irrelevant

Even if you run full dual stack (like i do) you will find that
normally connections are over ipv4 anyway.

Having said that, there is slowness to shutdown. I have seen that,
clearly some of the threads aren't shutting down in a timely manner.
(also applies to the backend)

I'll keep an eye out for startup slowness, but i've not seen that.
