What's the reason for locking the index? I would think that
merge_ort_nonrecursive() does not modify the index (in any case, I
removed the locking code and the tests still pass). And as for changes
in the worktree, I ran "strace" on the "stash apply" in the test and I
didn't see any changes in the worktree from here until the lock is
released.

Other than that, this patch set looks good to me.
