def get
  # If a DataSource hasn't been manually set when the first request is
  # made to obtain a DataSource, then a default data source is created.
  #
  # This is done at the first request rather than when TZInfo is loaded to
  # avoid unnecessary attempts to find a suitable DataSource.
  #
  # A `Mutex` is used to ensure that only a single default instance is
  # created (this avoiding the possibility of retaining two copies of the
  # same data in memory).
