<li>Bug fix: Ensure the cached KeyInfo objects (an internal abstraction not visible to the

    and reopening some database connections while leaving other database connections on the

    fail with an [SQLITE_ABORT] or [SQLITE_ABORT_ROLLBACK] error.  That error is still returned
    if the ROLLBACK modifies the schema.
