Your inner script looks kind of funny: you start a command, and wait for it to end. Maybe you have your reasons, but wouldn't
Code:
if hive ... # (without &)
then
echo Success
exit 0
fi
echo Failure
exit 1
have done the same with less fuss?

Also, aren't you making things too complicated, how about
Code:
for i in 1 4 2 3
do
(
echo Scripted error message >&2
ls nonexistent
sleep $i
) 1> out_$i 2> err_$i &
done
wait # all of them
for i in 1 4 2 3
do
if [ -s err_$i ]
then
echo Check errors in err_$i
fi
done

times - shell built-in function to report time usages of the current shell
SYNOPSIS
sh
times
ksh
times
DESCRIPTION
sh
Print the accumulated user and system times for processes run from the shell.
ksh
Print the accumulated user and system times for the shell and for processes run from the shell.
On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:
1. Variable assignment lists preceding the command remain in effect when the command completes.
2. I/O redirections are processed after variable assignments.
3. Errors cause a script that contains them to abort.
4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a
variable assignment. This means that tilde substitution is performed after the = sign and word splitting and file name genera-
tion are not performed.
