I came up with a solution, I don't think it's very pretty but it works.

GNU tail has a --pid option that waits for a process to exit, so my
screenrc has something like:

split -v
screen vim foo.txt
focus
screen shownotes foonotes.txt
focus

Where shownotes is a oneline shell script like this, adjust to taste:

#!/bin/bash
exec tail --sleep-interval=0.1 --lines=+0 --follow --pid=$(pgrep -P ${STY%%.*} 
-x vim) ${1}

Now when vim exits in the main region, the other region immediately quits.

If someone knows a less hacky solution, please let me know. Thought I'd
post this for anyone searching for a similar problem in future.

Tavis.
