FYI your e1a730017d6 patch introduces the following compiler warning:

process.c: In function ‘child_signal_notify’:
process.c:7436:54: warning: suggest braces around empty body in an ‘if’ 
statement [-Wempty-body]
 7436 |     /* emacs_perror ("writing to child signal FD") */;
      |                                                      ^
