Takes roughly twice the time. According to the BerkleyDB documentation
they consider it "good practice to set the DB_RECOVER and DB_CREATE for
every open". Unfortunately this is only possible for single-threaded
applications, which, to my understanding, is the reason why upstream did
not set the DB_RECOVER flags in torrus itself.

Just set the recover flag, as the underlying BerkleyDB function does
the check whether any action is necessary itself and in the normal case
returns very fast.
