i don't like the lenghty threads about this, but i've read them, the smartptr
passing mavens would have you pass the refptr by value and ideally std::move()
it into the datamember below

     : binding_(this, std::move(request)),
       directory_path_(directory_path),
       temp_dir_(std::move(temp_dir)),
       lock_table_(lock_table) {}
 
 DirectoryImpl::~DirectoryImpl() {
