Summary: Subclasses of IO do not ensure that IO#close is called in block form

Initial Comment:
This bug was introduced in Ruby 1.8.3 and still exists as of the nightly snapshot as of 30-Jun-2006, so I didn't want it forgotten.

class Foo < IO
    def close
       STDOUT.puts "Hello"
       super
    end
end

if $0 == __FILE__
    Foo.open(File.open("testio.txt","w+").fileno){ |fh|
       fh.puts "hello"
    }
end
