"Survive" how? by closing all the frames?

IOW, you are saying that when this happens, Emacs should test whether
it has a running server, and if it does, unconditionally close all the
frames?  Is that really useful?

Why not close Emacs before that -- this way you get to keep all your
edits, instead of relying on error handling to succeed in doing that.
