  New Revision: 67161

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=67161

  Log:
    do not close FSs explicitly.
    
    * test/ruby/test_dir.rb: r67159 closes all files explicitly
      but this change breaks attempt of this test introduced at
      r56467. Try another solution which removes all references
      from an Array with `#clear`.
