Subject: BFS revisited, brain fuck scheduling

Here's a somewhat imperfect, though short script I knocked together
that fixes scheduling issues.

while true
do
for i in `iotop -P -b -q -o -d 0.1 -n 10 | awk -F ' ' '{if ( $1 ~
/[0-9]/ && $10 > 10) print  $1}'`
do
        ionice -c 3 -p $i
       echo "process $i reniced to idel as it was hogging io"
done
for i in `top  -b -d 0.1 -n 10 | awk -F ' ' '{if ( $1 ~ /[0-9]/ && $4
== 0 && $9 > 15) print  $1}'`
do
        renice -n 10 -p $i
       echo "process $i reniced to idel as it was hogging cpu"
done
for i in `top  -b -d 0.1 -n 10 | awk -F ' ' '{if ( $1 ~ /[0-9]/ && $4
== 10 && $9 < 10) print  $1}'`
do
        renice -n 0 -p $i
       echo "process $i reniced to idel as it stopped hogging cpu"
done
sleep 0.5
done
