"--all" that tells "traverse from the tip of all the refs" to any rev-list family of commands (like log and bundle) eventually boils down to opendir("refs/...") followed by readdir(), and if somebody creates or deletes files while you are reading in such a loop, readdir() may appear to skip an entry, which is understandable. Even "git for-each-ref" would race with a ref update (which involves removing a file and then creating another file at the same path), I would think. IOW, I do not think this is limited to "git bundle".
