Yep. And that's bad. It means that ifupdown spawns dhclient, and
something else is doin' it too.

Aha. And this is that 'something else'. I don't use this abomination,
but [1] helpfully tell us:

Unmanaged devices means NetworkManager doesn't handle those network
devices. This occurs when two conditions are met:

The file /etc/network/interfaces contains anything about the interface,
even:

allow-hotplug eth0
iface eth0 inet dhcp

And /etc/NetworkManager/NetworkManager.conf contains:

[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=false
