Never mind -- after looking at the code, it is clear why it is blowing up. 
Can you explain what the unlock in the try-except block is supposed to be
doing?  Can that if-statement be safely deleted?

    def close(self):
        '''DB-API Cursor.close()
        '''
        self._lock()
        try:
            if self._state == _CUR_CLOSED:
                self._raise_error(Error, 'cursor is closed')
            if self._state != _CUR_IDLE:
                status = self._cmd.ct_cancel(CS_CANCEL_ALL)
                if status == CS_SUCCEED:
                    self._unlock()
            self._cmd = None
            self._state = _CUR_CLOSED
        finally:
            self._unlock()

Thanks,
