Whether the implementation is race-prone or not is an internal thing.
I wasn't referring to the internal implementation. I was referring to
cp users. With the newer Coreutils (FreeBSD) behavior, you can
reliably write a script to do something if cp -n didn't copy the file
because the destination already existed. With the older Coreutils
behavior you cannot do that reliably; there will always be a race
condition.
You can now reliably write a script using the new long option. Changing
the behavior of the short option helped nobody.
