Not 100%.
First of all desktop work is driver work. Desktop users tend to get pissed
if their shiny new webcam or DSL does not work.
And thinks like the hotplugging subsystems are essential.
Handling of removable media still is less than optimal.
Then there's the issue of application startup. There's not enough
read ahead. This is especially sad, as the order of page faults is at
least partially predictable.
Another thing that sucks in desktop enviroments is displaying directories.
Asynchronous IO will somewhat help, but you can't do an asynchronous stat.
Now do this while a compiler is running. Deadline IO scheduling will help
but a real helper would be read ahead on directory, inode and multi file
level.
