Isn't he talking about Boost intrusive lists?

http://www.boost.org/doc/libs/1_51_0/doc/html/intrusive/intrusive_vs_nontrusive.html

One advantage of the NOT intrusive stl list is that if you have 
to transverse the linked list very often, the L1 cache only sees 
the smal(ler) "helpers" (see this image: 
http://250bpm.wdfiles.com/local--files/blog:8/cpp1.png ) this 
probably leads to faster traversal times.

On the other hand linked lists are kind of dead, today their need 
is uncommon.
