Why all of the extra code motion and change?

Your description sounds like only the first hunk is necessary.  Did
something else get mixed into this change?  Or are all of the hunks
necessary?

Because after unsharing, pid_for_children is a dangling symlink.
So if (forkit) needs to be before /* wait for bind_ns_files_from_child() */. Moving this results in an overlapping use of the pid variable, so that gets renamed. Additionally, we cannot wait for the forkit child (bash) to exit before triggering and waiting for the bind-mounting child to bind-mount the persistent namespace. So forking and waiting for the forkit child (bash) needs to become splitted.
