Ok, thats a fair point. Now, what do you consider a heavy write I/O. Is
this script adequate, whilst continuing normal webserving?

#!/bin/sh
        for (( COUNT=1; COUNT < 10; COUNT++ )); do
                (dd if=/dev/zero bs=1024 count=10240000 | tee 1 | tee 2
| tee 3 | tee 4 > 5) > /dev/null 2>&1
                sync
                rm -f 1 2 3 4 5
                echo -n ">"

echo
