My version of the MySQL driver has JdmResultSet #flush.

I am not sure if I added it or it came stock or if I added it. I seem  
to remember it coming from a version of the driver but "versions"  
tell me I added it.

I have changed the drivers a bit to work with MySQL 4.1.8 (had some  
problems with dates) and to handle transactions.

The changes are minor but can be found at http://squeaksource.com/ 
IOSPersistent  .
