..and i cannot create a reproducer for the EXIT case as shown in
the last email: i think this really happens only in interactive
shells.
However, here is a very weird thing that shows multiple problems
of i think dash.  You get several different outputs for
  $ dash t.sh; DUDU=: dash t.sh
vs
  $ bash t.sh; DUDU=: bash t.sh

With DUDU=: the read does not "hang", as in the interactive case.
That is all i know.

I say Ciao! already here.

  : ${DUDU:='exit 0'}

  trap : EXIT

  doit() {
    PROCID=$$
    export PROCID
    trap "echo 'Timeout expired'; rm -f \"$TMPDIR\"/.$$.sh; eval $DUDU" QUIT
    /bin/sh -c '/bin/sleep 3 && kill -QUIT $PROCID' </dev/null >/dev/null 2>&1 &
    killer=$!
    read input
    kill -TERM $killer
    echo "input<$input>"
  }

  ___on_exit() {
    echo ex1
    . "$TMPDIR"/.$$.sh
    echo ex2
    doit
    echo ex3
  }
  trap ___on_exit EXIT

  { echo 'trap : EXIT'; echo 'rm -f "$TMPDIR"/.'$$'.sh'; echo 'doit'; } > "$TMPDIR"/.$$.sh
  echo 1
  alias l='echo -1'
  echo 2
  k= l=
  echo 3 && l=-2 || l=-3
  echo 4 && l='-2' || l='-3'
  echo 5
  exit
