Ruby - Ensure Syslog Gets Closed

class Foo
  def initialize
    @@log = Syslog.open("foo")
  end
end

class Foo
  def do_something
    Syslog.open do
      # work with the syslog here
    end
  end
end

class Foo
  def initialize
    @@log = Syslog.open("foo")
  end

  def Foo.finalize(id)
    @@log.close if @@log
  end
end
