Message:

New way to manage locks in window manager. Windows is locked with MPI_Win_lock_all at creation (shared mode), and lock is manage by software way in the class (using MPI_swap_and_compare and MPI_Fetch_op). We get in this case a better control of lock, with controled latency between each attemp of lock.
