Can anybody clarify the last line of the blog article [1]? The author makes it sound like storing data using $.data() is an async operation. The API docs make no mention of this. In some quick tests using Chrome, I was always able to immediately retrieve the value that was stored.

I'm actually planning on using this method, so I'd really like to know.

[1] "Furthermore, storing data takes a certain amount of time, so you might get a null exception if you are planning on retrieving it right after storage. There are currently no plans to add a callback to the jQuery data that I’m aware of."

Edit: $.data() seems to be async, but $(el).data() is not. At least that's what I found. Maybe that explains the difference in speeds.
