ctdb needs to develop a database model to distribute persistent handle
information across nodes. For larger clusters, this will probably also
require to introduce failover groups, you don't want to broadcast
persistent handle information everywhere. This needs to be developed
closely together with Samba, because right now Samba has no notion of
persistent handles. As you know, patches for persistent handles are
already floating around on the lists, but these need to be polished and
integrated into Samba.
