Should possibly fix unlimited WAL growing (like in ibireme#115) Cached prepared statements in _dbPrepareStmt are not reset until next call, so both automatic and manual checkpoints are failing to occur, causing WAL to grow and never to be merged into main DB file (see http://sqlite.1065341.n5.nabble.com/sqlite3-wal-checkpoint-v2-returning-SQLITE-LOCKED-in-what-circumstances-td86662.html)

There was a problem hiding this comment.
sqlite3_reset(stmt); should add before line:444 if (!inline_data || inline_data_bytes <= 0) return nil;
