Message:

Major update :

• New method to lock and unlock one-sided windows (window_dynamic) to avoid network overhead
• Introducing multithreading on server sided to manage more efficiently dead-lock occuring (similar to co-routine which will be available and implemented in futur c++ standard), based on c++ threads
• Suprression of old "attached mode" which is replaced by online writer and reder filters
