Grants first could hold back the very declaration that lets the controller issue them. The holder now goes first, then buckets and memberships, then the rest; a membership that fails holds back only its own machine, and an announcement whose send stopped at its grants is asked again. Whether the holder must go first is read from a digest of the user list it was last sent, not its whole declaration. Migration renumbered to 0058.

-- And the bus's user list the machine holding the bus was last sent, as a digest (novox/hq issue
