    167167=== 6.2) detailed destruction scenario ===
    168168
    169  1. To handle the sys_kill() or sys_exit() system call, the client thread calls directly the process_make_kill() or process_make_exit() function, or use the relevant RPC if it is not running in the owner  cluster.
     169 1. Both the sys_kill() or sys_exit() sys calls, use the rpc_process_make_kill_client(), to ask an RPC thread to execute the process_make_kill() function in the owner cluster (because a thread cannot kill itself).
    170170 1. The  process_make_kill() function in owner cluster send a multicast and parallel RPC to all clusters containing a copy of the process. In each cluster, the process_block_threads() function set the BLOCKED_GLOBAL bit for all threads of the process. It returns only when all threads are blocked and descheduled.
    171  1. When the process_make_kill() function in owner cluster has received all expected responses to the first multicast RPC, it send another multicast and parallel RPC to all clusters containing a copy of the process. In each cluster, the process_delete_threads() function releases the memory allocated to the local threads. The local process descriptor
    172 is also destroyed, if it is not the reference process descriptor.
