Just a note, NuDB does not have this property. It is entirely possible
that a call to nudb::store::insert will return, and if the database
crashes afterwards the inserted value will not be present in the
recovered database. This is by design.

All that NuDB assures is that for a suitable set of operating systems
and file systems, the recovered database will not be corrupt.
