Suppress directly calling function "add_entry" (accept db_file)
|

Pass a list of valid entries to a new function "add_entries"

(accept db_file) which would call function "add_entry" (accept cur).

* accelerate adding of large set of entries at once.

* prevent (or mitigate halt of consequent actions).
