Using jobs to count background jobs running:

Code:
#!/bin/ksh
PROCS=6
SLEEP=20
while read LINE
do
     while true
     do
         NUM=$(jobs | wc -l)
         echo NUM=$NUM
         if [ $NUM -lt $PROCS ]
         then
             stuff "$LINE" &
             break
         else
             sleep $SLEEP
         fi
    done
done < textfile
# wait for ALL remaining processes
wait
