Such that _exit calls itself recursively? (this was my first reading)

I don't see any useful code in sysdeps/unix/_exit.S.  Certainly not
anything that resembles an actual system call.  What do you mean?
Perhaps that the syscall code generated by syscalls.list should define
_exit as an alias to __syscall_exit?
