ENV.append "CFLAGS", "-O2 -DFD_SETSIZE=10000 -DDARWIN_UNLIMITED_SELECT"

darn - I still run out of files - is it possible @d12frosted to bump it up even more or expose it in the build flags , something --with-fd-size=..

@fxfactorial I am not sure it's a good idea to increase this limit even further, need to check with macos limits. Adding an option is not an option (pun not intended), because brew supports only boolean options. An alternative would be to `brew edit emacs-plus@30 (or whatever version you are using) and edit that number yourself before building Emacs again.
