Currently, I cannot get scripts with trap in them to work correctly
under bash version 1.12.1.  Here is a simple delay script that does
not work:

  delay=6
  trap 'trap 14' 14
  echo "What is your Quest? \c"
  (sleep $delay; kill -14 $$ 2>/dev/null)&
  read YourQuest
  kill $! 2>/dev/null
  [ ! -z "$YourQuest" ] && echo "Bah. Humbug. Not interested in $YourQuest" \
                        || echo "You must be interested in something!"

Similarly, the following script hangs at the "who am i" if the trap line
is there.  If the trap line is commented out, the scripts runs to completion.

  PATH=/bin:/usr/bin
  trap "" 1 2 3 4 5 6 7 8 '9' 10 11 12 13 14 15 16 17 18 \
                  19 20 21 22 23 24 25 26 27 28 29 30 31
  set - $(who am i)
  echo $1

Does anyone know of any patches for bash's signal handling code?
Thank you.
