One of the most frustrating things on the SO sites is, when I'm typing a large comment (or answer), and then it won't post, because the Q or A has been deleted. How about warning the deleter that someone is commenting (or answering) on his post?

+1 This has happened a couple times to me in the past, and it definitely is rather frustrating.
Perhaps a 30 second interval while editing to check the status, and pop in our favorite orange-bar when there's a major change in status...
This could be handy, but only if I can see what they're typing. If it's just a comment telling me what I already know (and what prompted me to delete the post in the first place...) then there's no reason I should wait around for them to finish writing it.
Such a feature would also allow me to preemptively respond to comments. Which could be fun.
