Sure it can be done, but it is not That's true. But it can be overcome by either using a database access daemon (wasteful) that all programs communicate with in order to access the database - it has the advantage that all the consistency checks are performed on one level - by the daemon and it's the daemon who serializes the database access. Second, the database itself could be optimized by using a different format (perhaps, as RPM does, a DB database?) to speed up searching it.
