This paper was published in early 2005, the research based on Linux 2.6.9,
which was released in 2004. The analysis was performed on code that is now
~6 years old.
Are these shortcomings valid? Have any been addressed/fixed since 2004?
Does real world usage show they're not needed, or that the development
cost/benefit ratio is too high to bother implementing the changes?
