Places like https://github.com/dmcgowan/docker/blob/containerd-integration/daemon/images/image_commit.go#L344 seem to not have protection for parallel requests that share a layer. This may cause failures caused by already locked reference. I haven't gone through all of the possible places where this can exist.
