I actually didn't make a single comment under that issue! Anyway, the problem is that if you have two entities that are not in a child-parent relationship, then you can't have a transaction that involves both. For example, you can't have a transaction involving two users of your app. So if a user performs an action that affects (e.g., the stats of) both, then you would have a problem in making sure that the stats are updated for both. This is a very fundamental flaw. I suspect that most GAE apps are incorrect due to this problem. Please vote up this issue. I realize that the GAE team would rather have someone implement an open source distributed transaction library for them. But I doubt this will happen any time soon. And even if it did, I would have more trust in an implementation by the GAE team anyway.
