davidxu 02615ff23a 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.
