Comment 7 for bug 501715

Hello people, it seems to me that this bug and bug 499773 are related.

In other word: when ureadahead does its retrace thing on boot, I see BOTH symptoms:

- the memory usage is very high

- the /var/lib/ureadahead/debugfs entry not removed from /etc/mtab

For a normal boot, when ureadahead retracing is not triggered, everything is normal.
