The counter will be 1 again. It shows 'how many events have occured 
since tarantool
startup`. An event here is user calling `box.schema.space.create`

Yes, it counts every space which was created with `box.schema.space.create`.

If you do `_space:insert{new_space_id, new_space_name, ...}` (I don't 
remember
the exact format but you get the idea), such an event won't
be counted.
