Emacs no longer hangs with the procedure to reproduce the problem.

I think resetting the SIGCHLD handler in the vfork child on Darwin is
still a good thing to do even with the change you installed, if the
SIGCHLD handler call in such a context is unexpected (and does not
happen on the other platforms).
