Reminds me of my need to be able to remove duplicate posts in which there is only a small difference.

I've seen multiple times that accepting a post after review took soooooo long that I got a timeout. After doing <back> and [create] again - maybe after adding a line to explain something that sprung up to add during the submission wait, both posts have been accepted even thought the first clearly gave the feedback of a timeout.

In this case I would love to be able to remove the first post.
