exec >&p
cat /etc/passwd
exitcode=$?
exec >&- >&4
wait
echo exitcode = $exitcode

I use this technique as well however, on occassion, I'll use the following, if I know that I'll be parsing the output anyway:
Code:
set -A ARRAY $(
somecommand
print RC=$?
)
for i in ${ARRAY[@]}
do
case $i in
RC*) ... ;;
whateverelse) ... ;;
esac
done
