# Pipes (and fifos), unix sockets and TTYs generate two fds in their ->open callbacls, the 2nd one can conflict with some other fd the task restores and (!) this "2nd one" may require sending to some other task. This imposes another requirement on the 3-stages engine described above.

# CTTYs should be __created__ after all other TTYs are created, configured and served out. Thus separate stages (not only queue) for CTTYs.
