Another thing we lost with current readahead (compared to what we had
with meego's readahead) is prefetching user session files (say
gnome-shell, files in /usr/share/applications, etc..), which, on
workstation used by a single user is really having an impact on
perceived system "speed" (ie when user can start working).
