Aha! This got me thinking...so I dug into the MySQLdb README file
(again). To be able to get a tuple of dictionaries returned while
using adbabi/MySQLdb, you simply have to do:
self.dbPool = adbapi.ConnectionPool("MySQLdb",host=host,port=port,
Since MySQLdb implements cursors in Python, one can subclass the base
cursor class or use one of the several others provided - in this case
DictCursor. This just wasn't obvious to me (never was) in the README!
