Comment 28 for bug 332790

ps auxw shows me the ionice'd process:
root 6466 0.0 0.0 4328 356 ? S 07:35 0:00 flock --nonblock /run/mlocate.daily.lock /usr/bin/ionice -c3 /usr/bin/updatedb.mlocate

but the problem process, blocking IO is:
root 6467 1.0 0.0 5688 2220 ? D 07:35 1:25 /usr/bin/updatedb.mlocate
It's this that eats nigh on 100% of IO. Is it a subprocess that's spawned and isn't ionice'd?
