bug#40023: 26.3 Emacs crashes when creating process if many file handles

Actually reducing RLIMIT_NOFILE doesn't sound like a terrific idea -- if 
anything, we need as many descriptors as we can get, in particular on macOS 
where kqueue uses up one per monitored file. If we are limited by FD_SETSIZE, 
then we shouldn't use select. Or am I missing something?
