          Returns a dictionary with keys identical to the stat C structure of stat(2).
          st_atime, st_mtime and st_ctime should be floats. On OSX, st_nlink should count
          all files inside the directory. On Linux, only the subdirectories are counted.

          except if the 'use_ino' mount option is given.
  
          This method gets very heavy traffic.
