Commit Message

zdtm: Add zombie01 test

Create a zombie with specific pgid and check that
pgid remains the same after restore.

This test hangs criu restore without any of two previous patches:
1)without "restore: Call prepare_fds() in restore_one_zombie()"
  in 100% cases;

2)without "restore: Split restore_one_helper() and wait exiting
  zombie children" fail is racy, but you can add something like

criu/cr-restore.c:
## -1130,6 +1130,8 @@ static int restore_one_zombie(CoreEntry *core)

        if (task_entries != NULL) {
                restore_finish_stage(task_entries, CR_STATE_RESTORE);
+               if (current->parent->pid->state == TASK_ALIVE)
+                       sleep(2);
                zombie_prepare_signals();
        }

and it will fail with almost 100% probability.
