We should explicitly initialise (and shut down) the SQLite library in the sqlite3 module. This may be required in future releases:

Quoting from the SQLite docs:
"For maximum portability, it is recommended that applications always invoke sqlite3_initialize() directly prior to using any other SQLite interface. Future releases of SQLite may require this. In other words, the behavior exhibited when SQLite is compiled with SQLITE_OMIT_AUTOINIT might become the default behavior in some future release of SQLite."
