I must be more precise:

I mean that when there is no writes, my scalable algorithms don't 
generate expensive cache-lines transfers on the reader side, this is why 
my scalable RWLocks algorithms are scalable on read mostly
scenarios.

I have done some empiric statistics with some benchmarks and i have
noticed that my scalable RWLocks scale even at 3% of writes.



Hope you have understood.
