If I load IPV6 as a module, it comes up with a ref count of 10
even though there are no applications using IPV6.
Interesting /proc/net/sockstat6 shows 1 TCP connection, but there is
no application with that open.
This doesn't seem right, and it makes unloading IPV6 impossible.

IPV6 is not safe to unload as a module, it is going to take
a lot of difficult work to fix this.
The 10 reference counts come from things like sockets created for
sending ipv6 ICMP packets and stuff like that.
