Because of this bug, clicking the "close" link on a question that's been edited (for me usually the edit comes in a half-second before, as I'm reaching for the link) reloads the question instead of opening the Close dialog. Clicking it again to actually open the close dialog says
You may only open the Close dialog every three seconds
I didn't open it, I refreshed the post.
And yes, there are lots of times when the post edit is so trivial it's obvious in less than a second that it doesn't affect the need to close the question.
