Oracle 11.2.0.2 Memory Bug

my installs for 11.2.0.2 were going on . I noticed something peculiar . The Memory utilization on my AIX Box was more than 10.2.0.4 . I looked at it and said well Maybe 11.2.0.2 needs more memory and brushed it off. That was till i read kurtvm's blog.
Apparently there is a bug
