prosody: Close the state on exit (ie garbage-collect everything) This ensures __gc is called on everything that may need it, such as database connections. It was reported in the chat by Happy that SQLite3 does not close its state cleanly in WAL mode, leaving the WAL file behind. This is probably rather a bug in mod_storage_sql, but forcing a final GC sweep should also help with such things everywhere.
