I agree that the EXIT trap should work on {} asynchronous subshells, and I
will make sure that the next version of bash does this.
However, the two examples you gave don't really differ in that respect. If
you take out the `kill', neither interactive nor non-interactive shells run
the exit trap. The difference is how interactive and non-interactive
shells handle SIGTERM. That's the place I'll have to look.
