Because storing the (persistent) handle state is only one part, the other one is
the FSA state.

Without extensive filesystem support with a lower level OS API for persistent
handles and a complete redesign of our durable and future persistent handle
support on top of that, we have to implement the required FSA state guarantees
in Samba and in clustered Samba.
