Bug description:
From time to time, some application uses 100% CPU but is not running
in foreground (not even in the list of recent application on the
application scope)
For example, in the top output below gallery-app uses 100% CPU, but it
is not 'launched' (not in recent apps)

I attached the output of strace for the gallery-app.
It is not specific to the gallery-app, I noticed this behavior with
system-settings too.
I didn't find any pattern to reproduce this problem reliably.
