Yes, my feeling has always been that this is an unlink (or generically,
"rm") race as I only saw it when two processes were processing file
removals (with one being "rm -rf") in two different directories.

Now what might be of relevance is that the two trees would have had
shared a high percentage of hard links. Maybe it's a race on deleting a
hard linked file?
