Right. But they are implemented as control_not_implemented(), so I
thought they would go soon as well.

For the pure process existence check I'd be happy to do what the local
check does: Look whether the process exists and the unique ID matches.
This can be done fine if every process registers both PID and unique
ID with the messaging-related CTDB_CONTROL_REGISTER_SRVID call. And
then have another control that checks both to exist on a single
socket. I know that's overloading the messaging IDs, but they are
kindof overloaded for local messaging too.
