It's discussed in the docs for the various DB calls (DB->open, etc):

DB_AUTO_COMMIT
    Enclose the DB->open call within a transaction. If the call
    succeeds, the open operation will be recoverable. If the call fails,
    no database will have been created.

The fact that a failed call won't change anything in the database, and
that a successful call will be recoverable, implies that the transaction
is either committed (and checlpointed), or aborted.
