Backs up what I thought git-annex should be doing; it's not fcntl locking that file.

Ah, I'll bet it's not git-annex at all this time.
It runs ssh with -S .git/annex/ssh/smaug, and ssh probably
does its own locking around setting up that control socket.

If so, disabling annex.sshcaching will avoid the problem.
