Try using the -u option of GNU parallel.

#!/bin/bash
# handle.sh
while true
do
echo "1\n2\n3" | parallel echo-u "$1-$RANDOM"
doneIX ./handle_X.sh

ThenThis runs them in parallel, running echo "1\n2\n3" | parallel -u ./handle.sh gives me continuous output from all streamswithout buffering the entirety of any process.

To split out to multiple scripts, try (untested): parallel -IX ./handle_X.sh
