While I still agree that the tests are overly simple, and don't really
give a good feel for a real world database, I just want to point out
that they have updated their testing and results to now include innodb
and berkely table types for mysql.
Sadly, they still do no transactions, they just compare single statement
innodb / berkely to myisam.
