This patch is more about servers than desktops.
This is a server with 1700 MB RAM, and it does quite a bit of IO:
# while true; do grep Dirty /proc/meminfo ; sleep 2s ; done
Dirty: 172404 kB
Dirty: 173100 kB
Dirty: 173332 kB
Dirty: 173260 kB
Dirty: 173692 kB
Dirty: 173684 kB
Dirty: 173724 kB
Dirty: 174256 kB
Dirty: 174772 kB
Dirty: 175120 kB

wouldn't this also be significantly about desktops ?
it seems the grandparent was talking about local disks only, even though article explicitly
mentions other use cases like nfs over gprs :) ).
desktops tend to have all kinds of relatively slow things connected to them - usb drives,
cameras, portable players, all kinds of slow network stuff...
if i understood the idea correctly, these could theoretically block/limit local hdd, which
would otherwise be the fastest device in an average desktop.
