Performance improvement by using several connections, instead of one big lock on the sqlite db for all threads. Several reads or reads + one write can go on simultaneously. Main benefit is that a long-going read such as a db snapshot no longer prevents all progress. Multiple writers still lock one another (like LMDB).
