That's unfortunate. The only remaining place to do that is in
ntdll/FILE_CreateFile and check for status code
STATUS_TOO_MANY_OPENED_FILES.

We can't differentiate between ENFILE (the global open file limit was
reached, given by fs.file-max sysctl) and EMFILE (RLIMIT_NOFILE was
reached), but that wouldn't be a problem since ENFILE should be rare
enough and there's also a KERN_INFO message to inform of that).

Also, would it be ok to call getrlimit from ntdll, wrapped in a
HAVE_SETRLIMIT ifdef (which is already used in libs/wine/loader.c)?
