    289289 * all threads of a process identified by the <pid> argument, depending on the
    290290 * <action_type> argument.
    291  * WARNING : the DELETE and BLOCK actions are NOT executed on the target process main thread
    292  * (thread 0 in process owner cluster), and not executed on the calling thread itself.
     291 *
    293292 * It uses the multicast, non blocking rpc_process_sigaction_client() function to send
    294293 * parallel requests to all remote clusters containing process copies.
     
    298297 * It is also used by the process_make_exec() function to handle the "exec" syscall.
    299298 * It is also called by the TXT device ISR to execute the ctrl C & ctrl Z commands.
     299 *
     300 * WARNING (1) the DELETE action is NOT executed on the target process main thread
     301 * (thread 0 in process owner cluster), and not executed on the client thread itself.
     302 *
     303 * WARNING (2) the BLOCK action is executed on all target process threads, and this function
     304 * returns only when all threads BUT the client thread are actually blocked and not running.
     305 * When the client thread is also a target thread, it is blocked but not descheduled.
     306 *
     307 * WARNING (3) the UNBLOCK action is executed on all target process threads, as the
     308 * client thread cannot be a target thread.
    300309 *
    301310 * Implementation note:
     
    328337 * It scan the list of local thread, and sets the THREAD_BLOCKED_GLOBAL bit for all threads.
    329338 * It request the relevant schedulers to acknowledge the blocking, using IPI if required,
    330  * and returns only when all threads in cluster are actually blocked.
     339 * and returns only when all threads in cluster, but the calling thread, are actually blocked.
    331340 * The threads are not detached from the scheduler, and not detached from the local process.
