   4 // issue arising from https://github.com/docker/docker/issues/27545,
   5 // which was initially fixed by https://github.com/docker/docker/pull/27884. But that fix
   6 // was too expensive in terms of performance on Windows. Instead,
   7 // https://github.com/docker/docker/pull/28514 introduces this new functionality
   8 // where the builder calls into the backend here to create the working directory.
