The comment immediately above this code says "don't allow local
clients to attach" and then looks up the client ID regardless of
whether the request is local or remote.
This means that an intentional remote attach from a client will not
work correctly. No real client should ever do that since clients
attach so they an access databases locally. Perhaps some sanity
checks should be added.

This broadcast is misnamed. Both places where this type of broadcast
is used expect the broadcast to go to all active nodes.
Make the corresponding change to the semantics in the daemon by
sending to all active nodes.
There is a mismatch between the ideas of VNN map and active nodes. A
node that is not in the VNN map but is active can still host database
records. These were the same until the LMASTER capability was
introduced and then the logic was not updated.
The only place where the VNN map is relevant is when finding the
location master of a record in the migration code.

Volatile databases now have their own subdirectory. This makes things
easier if we later recommend mounting a tmpfs on the volatile database
directory, rather than supporting the current CTDB_DBDIR=tmpfs magic.
