It's not really something to be fixed. It's more of a short term solution. That being said, Avi Bryant built DabbleDB based on image persistency.. basically (as I understand it) he created a minimal image for each project on there and just saved the data in that image.
GemStone does this (essentially), too, but with all the facilities a database should have. There's sandstonestone db (with the GOODS backend). You can get mysql drivers from squeaksource (not too bad to set up). There's a lot of persistency options.
