docstring: Retrieve a PEP 302 importer for the given path item
  
      The returned importer is cached in sys.path_importer_cache
      if it was newly created by a path hook.
  
      If there is no importer, a wrapper around the basic import
      machinery is returned. This wrapper is never inserted into
      the importer cache (None is inserted instead).
  
      The cache (or part of it) can be cleared manually if a
      rescan of sys.path_hooks is necessary.
