That restriction is only a current limitation of the tools. I simply
haven't taken the time to set the option at runtime.

What is wrong with {GET/SET}DOMAININFO? These can be done at run-time.
If you look, you'll see that I explicitly handle the case of removing
a domain from an existing group before adding it to another.

I'm perfectly happy to do that, but I'd like to know why SETDOMAININFO
doesn't fit the bill.

I would also appreciate feedback on the correctness of the locking.
