So really what we're searching for here is a workaround for a bug in a
different application that happens to be executing a zsh script.

Try this:
  trap 'setopt MONITOR HUP NOCHECKJOBS; exit' TERM

That won't kill an xterm process because xterm ignores SIGHUP, but it
should kill ssh-add.

That's ... interesting.  The error makes it look like ssh-askpass is
what's not being found, but it's probably choking trying to open a
terminal.  I can think of some possible ways to fake it but perhaps
with the above MONITOR tweak it isn't necessary.
