Review Comment:
   If so, we can reorder the code in _exit to correct the sequence. It can't 
resolve by introducing nx_exit. So, I would suggest that:
   
   Remove nx_exit
   Make exit as a normal libc function
   Make _exit as the kernel function
   atexit related function look in a good shape, the next step is simple now:
   
   Create a new patch to remove the kernel side atexit and enable libc's version
   Remove the exit callback from _exit
   The last step is moving file stream flush/close to the userspace. The last 
work is my TODO list, actually I have a draft patch in my local branch for it.
