Hello,


I think i have made a mistake about the follwing reader-writer lock of
Joe Duffy:

http://joeduffyblog.com/2009/02/20/a-more-scalable-readerwriter-lock-and-a-bit-less-harsh-consideration-of-the-idea/ 


Since a cache-line transfer between cores is not at all expensive,
so the serial part of the Amdahl's law for this reader-writer
above will still be smaller  with more and more cores,
so this will make this reader-writer lock above of Joe Duffy
really scalable on read-mostly scenarios.



Thank you,
Amine Moulay Ramdane.
