The cause of the corruption is believed to be an interaction between the
click-system-hooks and the apparmor upstart jobs. click-apparmor will be
adjusted to use a blocking lockfile to avoid the corruption. As such,
the apparmor task priority can be reduced.
After discussing with the apparmor team, fixing the parser bug can (and
should be done) but it more involved that the cache bug and we can't fix
it in time for rtm. If the lockfile doesn't fully address this issue, we
can go back to using '-n1' with xargs unconditionally in
/lib/apparmor/functions.
