  Log:
  Oops, forgot to update this file.
  Fix a race condition between kern_wait() and thread_stopped().
  Problem is in kern_wait(), parent process steps through children list,
  once a child process is skipped, and later even if the child is stopped,
  parent process still sleeps in msleep(), the race happens if parent
  masked SIGCHLD.
