1) Function scan at "for entry in entries"

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).

* reduce I/O.

2) Call sqlite function from function statistics.

Returning a list of values doesn't' seem to be a good practice.

3) Special statistics for operator:

* Amount of JIDs subscribed;

* Amount of feeds of all JIDs;

* Amount of entries of all JIDs.
