Domain creation at the moment is limited to privileged processes, because we have no limits for accounting or other safeguards in place. Domains are a conceptually bit closer to an OS container, applications should see a custom endpoint or can create their own private buses in the domain they run in. >> >> 2) What about creating custom endpoints on the bus that was already >> >> unrefed ?

I've committed a few more guards which check for disconnected, right before we try to link into the parent object.
