Enhance utils.ensure_dir to be resilient to concurrent workers

In rare cases, concurrent workers may attempt to ensure a directory
exists.  One may successfully create the directory while the other
gets an oserror that it already exists.  This patch detects the
problem and returns successfully in both cases.
