My first thought when reading this is "SQLite" (with the Python wrappers 
PySqlite or APSW).

See http://www.sqlite.org where it claims "Transactions are atomic, 
consistent, isolated, and durable (ACID) even after system crashes and 
power failures",

... or some of the sections in http://www.sqlite.org/lockingv3.html 
which provide more technical background.

If intending to rely on this for a mission critical system, one would be 
well advised to research independent analyses of the claims.
