* The underlying tables are all TDB tables.
* These TDB tables are of three types:
2) Normal ("volatile")
I think I generally understand how these work. I have some questions about
the sequence of events when writing to a Persistent TDB, but those can wait.

the only reader/writer to the local TDBs? For Normal LTDBs in
particular, is fcntl byte-range locking used to manage access in any
