I still think that ptrace() is not the best way to implement this kind
of security tool, and I think it's entirely understandable that they did
not use ptrace. I do not think it is a fair criticism of AppArmor to say
"AppArmor should have used ptrace()".

Take a look at utrace in -mm, it offers a completely backwards compatible
ptrace() syscall implemented as a module ontop of it. utrace looks like the
way things will be going forward
http://people.redhat.com/roland/utrace/2.6-current/0-intro.txt

Think of ptrace() implemented using utrace as ptrace that "Sucks Less TM".
Maybe Andy will let utrace out of -mm for 2.6.23.
