Every process now has an init process like it has a session, and each session belong to an init. Orphaned processes are reparented to its init process. All descendent processes are SIGKILL'd when an init process exits and creating additional processes/threads fails. Add setinit(2) for becoming the init process for your child processes and add getinit(2) for locating your init process. Add TIOCSCTTY force flag that releases a terminal from its current session and makes it the controlling terminal for the current session. This ioctl is essential to transferring the controlling terminal to a nested init, which has its own session. Add TIOCUCTTY that releases the terminal as the controlling terminal for its current session. Remove INIT_PID as it is replaced by getinit(2).
