I see your point and I agree that it's possible to make your app gracefully handle exceptions. However, there's no way Rails can automate it for you: you still have to carefully design your app to handle it.

If Rails can help you make it easier, that's great, I just don't see how it's a mostly-compatible solution as Yehuda wrote in the post.

I fully agree that we should explore this option, but at the same time we should make people aware of the trade-offs and not present it as some setting you can simply enable by config.automatic_flushing = true (which makes Rails do all the hard work).

Yehuda didn't even mention the word exception in the blog post, so I wasn't sure if was aware of the issues or not.
