Not a show-stopper for commit IMO.

It wouldn't be the first layerfs issue, so I wouldn't call this a show

concurrency issue. The bulk build is heavily utilising the unlink path
as well.

Me too. I have also seen one instance where the code seems to have been
spinning inside the kernel.

Nevertheless I do not believe this problems to be show-stoppers for
merging the code into HEAD.
