bug#33154: 27.0.50; create_process on Darwin should not invoke setsid() after vfork() [PATCH]

[Filipp Gunbin]

Paul, I think this won't work:

man tty (4):
     TIOCSCTTY void
                 Make the terminal the controlling terminal for the process
                 (the process must not currently have a controlling terminal).

In your patch, we don't detach from current (Emacs's) controlling
terminal before doing TIOCSCTTY.

I think what Alan meant as "reuse" was to extract the code into some
function.
