Which is bad enough if you say "ls". And there's no option to say "don't
sort" that I know of, either.
If you say "ls *" it's in some ways worse, in that the "*" is expanded by
the shell, and most of the filenames don't make it to ls at all. ("ls
abc*" is more likely, but with a million files that can still easily
overlow the argument limit.)
There really ought to be an option to make ls not sort, at least.
