For x-data-plane=true, we create an iothread automatically for
compatibility. Commit d21e877 ("iothread: include id in thread name")
exposed that this iothread missed correct parenthood: fix this.

Scratch that, does not work... (I thought I was hitting the other

Should I go ahead and apply Fam's "remove x-data-plane" patch then?
