You won't see this ([!=]= NULL) in the current code anymore.

DESCRIPTION
       _exit terminates the calling process immediately. Any open file
       descriptors belonging to the process are closed; any children
       of the process are inherited by process 1, init, and the
       process's parent is sent a SIGCHLD signal.

       status is returned to the parent process as the process's exit
       status, and can be collected using one of the
       wait family of calls.

RETURN VALUE
       _exit never returns.

CONFORMING TO
       SVr4, SVID, POSIX, X/OPEN, BSD 4.3

NOTES
       _exit does not call any functions registered with the ANSI C
       atexit function and does not flush standard I/O
       buffers. To do these things, use exit(3).
