  ==> Should be much faster since there is much less CAS operations performed and GC is perfomed per block.
 
+ Tests have been done:
+ - Performance is good. (8.9s even if most of the bench times is lost in usleep)
+ Real performance (without usleep) is 3x faster.
+ - Integrity seems ok after lot of debug. Lock Free algorithm are definitly not trivial,
+ even when implementing well known algorithms!
