Fine by me to remove that :)

What about replacing the XXX comment by a small note, say:
"On Windows, using a hard link followed by an unlink() causes
concurrency issues with code paths interacting with those files, a
rename does not cause that."

If you have a better idea, which I am sure you do, please feel free to
send suggestions.
