I honestly still think it's dumb luck. Are you never getting them out, or only intermittently like me? I can't see reflashing as being the issue. There are long ongoing sagas of home remedies on the handcent forums, every now and then having them call it "solved". Many of the users are on stock ROMs, so I doubt reflashing has more magic than any other proposed fix. There's a real issue somewhere in their code and it's an intermittent bug, not just individual phone corruption. It's too widespread to be that.
