A change was made in the last CL to ask sqlite for all unfinalized statements
and then finalizing them before closing the database.
But this crashes sqlite! because sqlite's FTS3
module keeps some prepared statements around and they should not
be finalized before closing the database.
(when sqlite is asked for all unfianlized statements, it also returns
the FTS3's reserved prepared statements which should not be
finalized!!)
