> 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?

We are talking about the emacs-27 branch, where such deep changes are
out of the question.
