And at worst? I guess I should have explained it a bit differently - yes
the operations may very well be on the global GTT, but for the given
reason (in the table), we need to make sure we unbind (or assert the
object isn't bound) in another address space first.

Possibly I've misunderstood what you'd like me to do however.
