Exactly right.  Uploads straight to S3 from the browser are fantastic,
you should use them if you're doing any kind of substantial upload
processing.

Moral of the story: never, ever block the web process for long (> 1
second) periods of time - there's always a better way.  Follow this
practice and you and your users will always be happy campers.

I certainly extend my apologies to you, Christos, and anyone else
inconvenienced by the incorrect docs.  I've tweaked the performance
concepts doc to remove some of the more glaring inaccuracies, which
will hopefully tide us over until we can rewrite the whole thing to
cover the broader array of concurrency models we can handle.
